Overview

Open Transport is the Mac OS 8 and 9 API for accessing TCP/IP networks, such as the Internet, at the transport level. For Mac OS X, Apple provides Open Transport as a compatibility library to ease migration of legacy applications. As such, Mac OS X does not support the entire Open Transport API.

In new Mac OS X applications you should not use Open Transport but should instead use BSD Sockets or, when possible, higher-level Core Services and Core Foundation APIs such as CFNetwork, CFURL, CFSocket, and CFStream. You can also use Cocoa networking classes such as NSURL, NSURLHandle, and NSNetService.

In Mac OS X, Open Transport provides limited support for endpoints and port access, and no support for the XTI or UNIX STREAMS interfaces. If you want your application to run in Mac OS 8 and 9 and in Mac OS X, use Open Transport for your Mac OS 8 and 9 version and Apple’s newer APIs for your Mac OS X version.

For more information about Open Transport, see:

http://developer.apple.com/macos/opentransport/

Mac OS X supports only these Open Transport providers:

Mac OS X does not support ADSP, ATP, ASP, PAP, or serial endpoints.

You may have to revise your code if it uses Open Transport in one of the following ways:

Mac OS X does not support functions for:

Client context parameters have been added to a number of OT functions. (An OT client is an application or a shared library.) Each client of Open Transport now has its own client context so that OT can track resources it allocates on behalf of the client. OT resources are objects like endpoints, timer tasks, and blocks of memory. To find out more about Open Transport resources management, see “Understanding Open Transport Asset Tracking” at:

http://developer.apple.com/technotes/tn/tn1173.html

Mac OS X introduces a new type, OTClientContextPtr, that represents the OT client context. This new type is passed as an extra parameter to functions that allocate OT resources. Before Mac OS X, the OT client context was determined by the Open Transport static libraries that you linked to your application. Now the OT client context is determined explicitly. The same Carbon binary can run on Mac OS 8/9 and Mac OS X, and you do not have to link your application to the static libraries.

You can use InitOpenTransportinContext to replace InitOpenTransport. It functions identically except that it also takes a client context pointer and a flags parameter to indicate whether you are initializing OT for an application or a shared library. When your application or shared library is done using Open Transport you should call CloseOpenTransportInContext to dispose of the Open Transport resources allocated for the client.

The following functions now take a client context:

As a convenience, applications may pass a null pointer to these routines and Open Transport will use the context that was passed to InitOpenTransport. However, shared libraries must always pass a valid OTClientContextPtr.

If you want to keep your application source code compatible with pre-Mac OS X systems, you may define the C preprocessor constant OTCARBONAPPLICATION to 1 to use the old routine names without the “InContext” suffix.

Mac OS X applications must pass UPPs instead of procedure pointers for Open Transport callback routines. You can use these new functions to create UPPs:

OTNotifyUPP replaces OTNotifyProcPtr

OTProcessUPP replaces OTNotifyProcPtr

OTListSearchUPP replaces OTListSearchProcPtr

You can use these functions to allocate and free UPPs:

These functions have been modified to take an OTNotifyUPP UPP instead of a procedure pointer:

These functions have been modified to take an OTProcessUPP UPP instead of a procedure pointer:

These functions have been modified to take an OTListSearchUPP UPP instead of a procedure pointer:

DNS Address Structure

Holds host names, partially or fully-qualified domain names, or dotted-decimal format Internet addresses for use with a variety of Open Transport functions.

struct DNSAddress {
   OTAddressType fAddressType;
   InetDomainName fName;
};
typedef struct DNSAddress DNSAddress;

Fields
fAddressType

The address type. For a DNSAddress structure, this should be AF_DNS.

fName

The name to be resolved by the DNR.

Discussion

You can use the DNS (domain name system) address structure with the OTConnect function (TCP), with the OTSndUData function (UDP), or with the OTResolveAddress function (either TCP or UDP). If you do so, TCP/IP will resolve the name for you automatically. You can use the OTInitDNSAddress function to fill in a DNS address structure. The DNS address structure is defined by the DNSAddress data type.

The address you specify can be just the host name (“otteam”), a partially qualified domain name (“otteam.ssw”), a fully qualified domain name (“otteam.ssw.apple.com.”), or an internet address in dotted-decimal format (“17.202.99.99”), and can optionally include a port number (“otteam.ssw.apple.com:25” or “17.202.99.99:25”).

Because the port number is not actually part of the domain name, it is possible to have a domain name–port number combination that exceeds 255 bytes. If you wish to specify such a string, you must provide a structure based on the DNS address structure that has sufficient space to contain the full string. In any case, the domain name itself cannot exceed 255 bytes.

DNS Query Information Structure

Returns answers to DNS queries.

   InetDomainName name;
   UInt16 responseType;
   UInt16 resourceLen;
   char resourceData[4];
};
typedef struct DNSQueryInfo DNSQueryInfo;

Fields
qType

The numerical value of the DNS resource record type, such as MX and PTR, for which you wish to query.

qClass

The numerical value of the DNS record class, such as Inet and Hesio, for which you wish to query.

ttl

An integer indicating the DNS resource record’s time to live (in seconds).

name

The fully qualified domain name or address for which you made the query.

responseType

The type of response.

resourceLen

The actual length of the resource data returned.

resourceData

The resource data that is returned. This is at least 4 bytes long, and is usually longer.

Discussion

The DNS query information structure is used by the TCP/IP service provider to return answers to DNS queries made using the OTInetQuery function. The DNS query information structure is defined by the DNSQueryInfo data type. For additional information about the constant values for the DNSQueryInfo fields, see the DNS Requests for Comments (RFCs), available over the World Wide Web.

See the Internet Standard for a definitive list of values for the qType, qClass, and respnoseType fields, and for a definition of the format of the resource data.

fNext


A pointer to the next OTBuffer structure in the linked chain. By tracing the chain of fNext pointers, you can access all of the data associated with the message. 


fData


A pointer to the data portion of this OTBuffer structure.


fLen


The length of data pointed to by the fData field.


fSave


Reserved.


fBand


The band used for the data transmission. It must be a value between 0 and 255.


fType


The type of the data (normally M_DATA, M_PROTO, or M_PCPROTO).


fPad1


Reserved.


fFlags


The flags associated with the data (MSGMARK, MSGDELIM).


Discussion


You use the no-copy receive buffer structure when you wish to receive data without copying it with the OTRcvUData function, the OTRcvURequest function, the OTRcvUReply function, the OTRcv function, the OTRcvRequest function, and the OTRcvReply function. 


If you are familiar with STREAMS mblk_t data structures, you can see that the no-copy receive buffer structure is just a slight modification of the mblk_t structure.


You can only use this buffer for data; you cannot use it for the address or options that may be associated with the incoming data. For example, in the case of an incoming TUnitData structure, you can only no-copy receive the udata portion, not the addr or opt fields. 


Special Considerations


Under no circumstance write to this data structure. It is read-only. If you write to it, you can crash the system.

Discussion


The buffer information structure is provided for your convenience in keeping track of where you last left off in an OTBuffer structure. Because the no-copy receive buffer structure (OTBuffer) is read-only, you may need to copy the data in sections as you progress through the no-copy receive buffer. The utility function OTReadBuffer is used with this structure to easily copy the data out of an OTBuffer structure.

fNext


A pointer to the OTData structure that describes the next data fragment. Specify a NULL pointer for the last data fragment.


fData


A pointer to the data fragment.


fLen


Specifies the size of the fragment in bytes.


Discussion


The OTData structure is an Apple extension used to specify the location and size of noncontiguous data. You use a pointer to this structure in place of a pointer to continguous data normally referenced in TNetbuf.buf field. You can send discontiguous data using the OTSndUData function, the OTSndURequest function, the OTSndUReply function, the OTSnd function, the OTSndRequest function, and the OTSndReply function.


Each OTData structure specifies the location of a data fragment, the size of the fragment, and the location of the OTData structure that specifies the location and size of the next data fragment. The data information structure is defined by the OTData type. For more information, see “Sending Noncontiguous Data.”

OTPortCloseStruct


Denies or accepts requests to yield a port.


struct OTPortCloseStruct {
   OTPortRef fPortRef;
   ProviderRef fTheProvider;
   OSStatus fDenyReason;
};
typedef struct OTPortCloseStruct OTPortCloseStruct;



Fields


fPortRef


The port requested to be closed. 


fTheProvider


The provider that is currently using the port. 


fDenyReason


A value that you can leave untouched to accept the yield request. To deny the request, change this value to a negative error code corresponding to the reason for your denial (normally you use the kOTUserRequestedErr error).


Discussion


When you are using a port that another client wishes to use, the other client can use the OTYieldPortRequest function (not available in Mac OS X) to ask you to yield the port. If you are registered as a client of Open Transport, you receive a kOTYieldPortRequest event, whose cookie parameter is a pointer to a port close structure. You can use this structure to deny or accept the yield request.


Currently, this callback is only used for serial ports, but it is applicable to any hardware device that cannot share a port with multiple clients. You should check the kOTCanYieldPort bit in the port structure’s fInfoFlags field to see whether the port supports yielding.


If the provider is passively listening (that is, bound with a queue length (qlen) greater than 0) and you are willing to yield, you need do nothing. If, however, you are actively connected and you are willing to yield the port, you must issue a synchronous OTSndDisconnect callin order to let the port go.

The Port Structure


Describes a port’s characteristics.


struct OTPortRecord {
   OTPortRef fRef;
   UInt32 fPortFlags;
   UInt32 fInfoFlags;
   UInt32 fCapabilities;
   ItemCount fNumChildPorts;
   OTPortRef * fChildPorts;
   char fPortName[36];
   char fModuleName[32];
   char fSlotID[8];
   char fResourceInfo[32];
   char fReserved[164];
};
typedef struct OTPortRecord OTPortRecord;



Fields


fRef


The port reference; a 32-bit value encoding the port’s device type, bus type, slot number, and multiport identifier


fPortFlags


Flags describing the port’s status. If no bits are set, the port is currently inactive—that is, it is not in use at this time.


fInfoFlags




fCapabilities




fNumChildPorts




fChildPorts


An array of the port references for the child ports associated with this port. When you get a Port Record, this pointer typically points into the SReserved field at the end of the record.


fPortName


A unique name for this port. The port name is a zero-terminated string that can have a maximum length as indicated by the constant kMaxProviderNameSize.


fModuleName


The name of the actual STREAMS module that implements the driver for this port. Open Transport uses this name internally; applications rarely need to use this name.


fSlotID


An 8-byte identifier for a port’s slot that contains a 7-byte character string plus a zero for termination. This identifier is typically available only for PCI cards.


fResourceInfo


A zero-terminated string that describes a shared library that can handle configuration information for the device. This field contains an identifier that allows Open Transport to access auxiliary information about the driver (Open Transport creates shared library IDs from this string to be able to find these extra shared libraries). This string should either be unique to the driver or should be set to a NULL string.


fReserved


Reserved.


Discussion


Open Transport uses a port structure to describe a port’s characteristics, such as its port name, its child ports, whether it is active or disabled, whether it is private or shareable, and the kind of framing it can use.

Timestamp Data Type


Contains an Open Transport timestamp.


typedef UnsignedWide OTTimeStamp;



Discussion


The timestamp data type is a 64-bit value that contains an Open Transport timestamp. The timestamp has unspecified units; you must use one of the timestamp manipulation functions described in “Timestamp Utility Functions” to convert the timestamp to known quantities. The timestamp data type is defined by the OTTimeStamp data type.

TBind


Describes the protocol address to which an endpoint is currently bound or connected, or specifies the protocol address to which you wish to bind or connect the endpoint.


struct TBind {
   TNetbuf addr;
   OTQLen qlen;
};
typedef struct TBind TBind;



Fields


addr


A TNetbuf structure that contains information about an address. The addr.maxlen field specifies the maximum size of the address, the addr.len field specifies the actual length of the address, and the addr.buf field points to the buffer containing the address. 
When specifying an address, you must allocate a buffer for the address and initialize it; you must set the addr.buf field to point to this buffer; and you must set the addr.len field to the size of the address.
When requesting an address, you must allocate a buffer in which the address is to be placed; you must set the addr.buf field to point to this buffer; and you must set the addr.maxlen field to the maximum size of the address that is being returned. You determine this value by examining the addr field of the TEndpointInfo structure for the endpoint.


qlen


For a connection-oriented endpoint, the maximum number of connection requests that can be concurrently outstanding for this endpoint. For more information, see the description of the OTBind function. For connectionless endpoints, this field has no meaning. 


Discussion


The TBind structure describes the protocol address to which an endpoint is currently bound or connected, or specifies the protocol address to which you wish to bind or connect the endpoint. For a connection-oriented endpoint, the TBind structure also specifies the actual or desired number of connection requests that can be concurrently outstanding for the endpoint. 


You pass the TBind structure as a parameter to the OTBind function, the OTGetProtAddress function, and the OTResolveAddress function.

TCall


Specifies the options and data associated with establishing a connection.


struct TCall {
   TNetbuf addr;
   TNetbuf opt;
   TNetbuf udata;
   OTSequence sequence;
};
typedef struct TCall TCall;



Fields


addr


A TNetbuf structure that specifies the location and size of an address buffer 


opt


A TNetbuf structure that specifies the location and size of an options buffer. 


udata


A TNetbuf structure that specifies the location and size of a buffer for data associated with a connection or disconnection request. 


sequence


A 32-bit value used by the OTListen and OTAccept functions to specify the connection ID. 


Discussion


You use the TCall structure to specify the options and data associated with establishing a connection. You pass a pointer to this structure as a parameter to the OTConnect function, the OTRcvConnect function, the OTListen function, and the OTAccept function.


If you are using the TCall structure to send information, you must allocate a buffer and initialize it to contain the information. Set the .buf field of each TNetbuf to point to the buffer, and then specify the size of the buffer using the .len field. Set this field to 0 if you are not sending data.


If you are using the TCall structure to receive information, you must allocate a buffer into which the function can place the information when it returns. Then set the .buf field of all the TNetbufs to point to this buffer, and set the .maxlen field to the maximum size of the information. Set this field to 0 if you are not interested in receiving information.

struct TDiscon {
   TNetbuf udata;
   OTReason reason;
   OTSequence sequence;
};
typedef struct TDiscon TDiscon;



Fields


udata


A TNetbuf structure that references data sent with the OTSndDisconnect function or received by the OTRcvDisconnect function. 


reason


A 32-bit value specifying an error code that identifies the reason for the disconnection. These codes are supplied by the protocol. For additional information, consult the documentation provided for the protocol you are using. 


sequence


A 32-bit value specifying an outstanding connection request that has been rejected. This field is meaningful only when you have issued several connection requests to the same endpoint and are awaiting the results.

   OTDataSize options;
   OTDataSize tsdu;
   OTDataSize etsdu;
   OTDataSize connect;
   OTDataSize discon;
   OTServiceType servtype;
   UInt32 flags;
};
typedef struct TEndpointInfo TEndpointInfo;



Fields


addr




options


A value greater than or equal to 0 indicates the maximum number of bytes needed to store the protocol-specific options that this endpoint supports, if any. A value of T_INVALID (-2) indicates that this endpoint has no protocol-specific options that you can set; they are read-only. A value of -3 specifies that the provider does not support any options. 


tsdu


For a transactionless endpoint, a positive value indicates the maximum number of bytes in a transport service data unit (TSDU) for this endpoint. A value of T_INFINITE (-1) indicates that there is no limit to the size of a TSDU. A value of 0 indicates that the provider does not support the concept of a TSDU. This means that you cannot send data with logical boundaries preserved across a connection. A value of T_INVALID indicates that this endpoint cannot transfer normal data (as opposed to expedited data). 
For a transaction-based endpoint, this field indicates the maximum number of bytes in a response. 


etsdu


For a transactionless endpoint, a positive value indicates the maximum number of bytes in an expedited transport service data unit (ETSDU) for this endpoint. A value of T_INFINITE indicates that there is no limit to the size of a ETSDU. A value of 0 indicates that this endpoint does not support the concept of an ETSDU. This means that you must not send expedited data with logical boundaries preserved across a connection. A value of T_INVALID indicates that this endpoint cannot transfer expedited data.
For a transaction-based endpoint, this field indicates the maximum number of bytes in a request. 


connect


For a connection-oriented endpoint, a value greater than or equal to 0 indicates the maximum amount of data (in bytes) that you can send with the OTConnect function or the OTAccept function. A value of T_INVALID indicates that this endpoint does not let you send data with these functions. This field is meaningless for other types of endpoints.


discon


For a connection-oriented endpoint, a value greater than or equal to 0 indicates the maximum amount of data (in bytes) that you can send using the OTSndDisconnect function. A value of T_INVALID indicates that this endpoint does not let you send data with disconnection requests. This field is meaningless for other types of endpoints.


servtype


A constant that indicates what kind of service the endpoint provides. Possible values are given by the “Endpoint Service Types” enumeration.


flags


A bit FIeld that provides additional information about the endpoint. Possible values are given by the “Endpoint Flags” enumeration.

struct TLookupBuffer {
   UInt16 fAddressLength;
   UInt16 fNameLength;
   UInt8 fAddressBuffer[1];
};
typedef struct TLookupBuffer TLookupBuffer;



Fields


fAddressLength


Specifies the size of the address specified by the fAddressBuffer field.


fNameLength


Specifies the size of the name that is stored in the buffer following the fAddressBuffer field.


fAddressBuffer


The first byte of the address to which the entity whose name follows (in the buffer) is bound. 


Discussion


The TLookupBuffer structure defines the format of entries in the buffer passed back in the reply parameter of the OTLookupName function. When you parse the buffer in which the OTLookupName function places the names it has found, you can cast it as a TLookupBuffer structure.
Availability

TLookupReply


Stores information passed back to your application by the OTLookupName function.


struct TLookupReply {
   TNetbuf names;
   UInt32 rspcount;
};
typedef struct TLookupReply TLookupReply;



Fields


names


A TNetbuf structure that specifies the size and location of a buffer into which the OTLookupName function, on return, places the names it has found. You must allocate the buffer into which the replies are stored when the function returns; you must set the names.buf field to point to it; and you must set the names.maxlen field to the size of the buffer. 


rspcount


A long specifying, on return, the number of names found.


Discussion


You use the TLookupReply structure to store information passed back to you by the OTLookupName function. The information includes both a pointer to a buffer (containing registered entity names matching the criterion specified with the TLookupRequest structure) and the number of names found.
Availability
Declared In
OpenTransport.h


TLookupRequest


Specifies the entity name to be looked up by the OTLookupName function.


struct TLookupRequest {
   TNetbuf name;
   TNetbuf addr;
   UInt32 maxcnt;
   OTTimeout timeout;
   OTFlags flags;
};
typedef struct TLookupRequest TLookupRequest;



Fields


name


A TNetbuf structure specifying the location and size of a buffer that contains the name to be looked up. You must allocate a buffer that contains the name, set the name.buf field to point to it, and set the name.len field to the length of the name.


addr


A TNetbuf structure describing the address of the node where you expect the names to be stored. You should normally supply 0 for addr.len. This causes the provider to use internal defaults for the starting point of the search. For a protocol family such as AppleTalk, in which every node has access to name and address information, this parameter is meaningless.
Specifying an address has meaning for those protocols that use a dedicated server or other device to store name information. In such a case, the name specified would override the protocol’s default address. To specify an address, you would need to allocate a buffer containing the address, set the addr.buf field to point to it, and set the addr.len field to the length of the address. Consult the documentation supplied with your protocol to determine whether you can or should specify an address.
 


maxcnt


A long specifying the number of names you expect to be returned. Some protocols allow the use of wildcard characters in specifying a name. As a result, the OTLookupName function might find multiple names matching the specified name pattern. If you expect a specific number of replies for a particular name or do not expect to exceed a specific number, you should specify this number to obtain faster execution. Otherwise, set this field to 0xffff ffff; in this case, the timeout value will control the lookup.


timeout


A long specifying the amount of time, in milliseconds, that should elapse before Open Transport gives up searching for a name. Specify 0 to leave the timeout value up to the underlying naming system. 


flags




Discussion


You use the TLookupRequest structure to specify the entity name to be looked up by the OTLookupName function and to set additional values that the mapper provider uses to circumscribe the search.

TNetbuf


Specifies the location and size of a buffer that contains an address, option information, or user data.


struct TNetbuf {
   ByteCount maxlen;
   ByteCount len;
   UInt8 * buf;
};
typedef struct TNetbuf TNetbuf;



Fields


maxlen


The size (in bytes) of the buffer to which the buf field points. You must set the maxlen field before passing a TNetbuf structure to a provider function as an output parameter. Open Transport ignores this field if you pass the TNetbuf structure as an input parameter.


len


The actual length (in bytes) of the information in the buffer to which the buf field points. If you are using the TNetbuf structure as an input parameter, you must set this field.
If you pass the TNetbuf structure as an output parameter, on return the provider function sets this field to the number of bytes the function has actually placed in the buffer referenced by the buf field.


buf


A pointer to a buffer. You must make sure that the buf field points to a valid buffer and that the buffer is large enough to store the information for which it is intended.


Discussion


You use a TNetbuf structure to specify the location and size of a buffer that contains an address, option information, or user data. Provider functions use TNetbuf structures both as input parameters and output parameters. If you use a TNetbuf structure as an input parameter, you specify the location and size of a buffer containing information you want to send. If you use a TNetbuf structure as an output parameter, you specify the location and the maximum size of the buffer used to hold information when the function returns.


You use a TNetbuf structure to describe the location and size of contiguous data. Open Transport allows you to describe noncontiguous data with the OTData structure.

};
typedef struct TOption TOption;



Fields


len

level


The protocol for which the option is defined. 


name


The name of the option. 


status


A status code specifying whether the negotiation has succeeded or failed. Possible values are given by the “Open Transport Flags and Status Codes” enumeration 


value


The option value. To have the endpoint select an appropriate value, you can specify the constant T_UNSPEC.


Discussion


The TOption structure stores information about a single option in a buffer. All functions that you use to change or verify option values use a buffer containing TOption structures to store option information. For each option in the buffer, the TOption structure specifies the total length occupied by the option, the protocol level of the option, the option name, the status of a negotiated value, and the value of the option.


You use the TOption structure with the OPT_NEXTHDR macro, the OTCreateOptionString function, the OTNextOption function, and the OTFindOption function.

The Option Management Structure


Manages the req and ret parameters of the OTOptionManagement function


struct TOptMgmt {
   TNetbuf opt;
   OTFlags flags;
};
typedef struct TOptMgmt TOptMgmt;



Fields


opt


A TNetbuf structure describing the buffer containing option information. The opt.maxlen field specifies the maximum size of the buffer. The opt.len field specifies the actual size of the buffer, and the opt.buf field contains the address of the buffer.
On input, as part of the req parameter, the buffer contains TOption structures describing the options to be negotiated or verified, or contains the names of options whose default or current values you are interested in. You must allocate this buffer, place in it the structures describing the options of interest, and set the opt.len field to the size of the buffer.
On output, as part of the ret parameter, the buffer contains the actual values of the options you described in the req parameter. You must allocate a buffer to hold the option information when the function returns and set the opt.maxlen field to the maximum length of this buffer. When the function returns, the opt.len field is set to the actual length of the buffer.

For the req parameter, the flags field indicates the action to be taken as defined by the action flags enumeration (page 570). For the ret parameter, the flags field indicates the overall success or failure of the operation performed by the OTOptionManagement function, as defined by the “Open Transport Flags and Status Codes” enumeration. 


Discussion


The option management structure is used for the req and ret parameters of the OTOptionManagement function. The req parameter is used to verify or negotiate option values. The ret parameter returns information about an endpoint’s default, current, or negotiated values.

TRegisterReply


Stores information returned by the OTRegisterName function.


struct TRegisterReply {

typedef struct TRegisterReply TRegisterReply;



Fields


addr


A TNetbuf structure that specifies the location and size of a buffer containing the actual address of the entity whose name you have just registered. This information is passed back to you when the OTRegisterName function returns. You must allocate a buffer, set the addr.buf field to point to it, and set the addr.maxlen field to the size of the buffer. 


nameid


A unique identifier passed to you when the OTRegisterName function returns. You can use this identifier when you call the OTDeleteNameByID function to delete the name.

   OTFlags flags;
};
typedef struct TRegisterRequest TRegisterRequest;



Fields


name


A TNetbuf structure that specifies the location and size of a buffer containing the entity name you want to register. You must allocate a buffer that contains the name, set the name.buf field to point to that buffer, and set the name.len field to the length of the buffer.


addr


A TNetbuf structure that specifies the location and size of a buffer containing the address associated with the entity whose name you want to register. You must allocate a buffer that contains the address, set the addr.buf field to point to that buffer, and set the addr.len field to the length of the buffer. The actual address with which the entity is associated is returned in the addr field of the TRegisterReply structure.
You can set the addr.len field to 0, in which case the underlying protocol finds an appropriate address to associate with the newly registered entity name.


flags


A field used to control registration. Normally, this field is set to 0 for default registration behavior. See the documentation for the naming service you are using for more information.

typedef struct TUDErr TUDErr;



Fields


addr


A TNetbuf structure that contains information about the destination address of the data sent using the OTSndUData function. The OTRcvUData function fills in the buffer referenced by this structure when the function returns. You must allocate a buffer to contain the address, initialize the addr.buf field to point to it, and set the addr.maxlen field to specify its maximum size. If you are not interested in address information, set addr.maxlen to 0. 


opt


A TNetbuf structure that contains information about the options associated with the data sent using the OTSndUDatafunction. The OTRcvUDErr function fills in the buffer referenced by this structure when the function returns. If you want to know this information, you must allocate a buffer to contain the option data, initialize the opt.buf field to point to it, and initialize the opt.maxlen field to specify the maximum size of the buffer. If you are not interested in option information, set the opt.maxlen field to 0. 


error


On return, this specifies a protocol-dependent error code for the OTSndUData function that failed.

Constants


T_LISTEN


A connection request has arrived. Call the OTListen function to read the request.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_CONNECT


The passive peer has accepted a connection that you requested using the OTConnect function. Call the OTRcvConnect function to retrieve any data or option information that the passive peer has specified when accepting the connection or to retrieve the address to which you are actually connected. The cookie parameter to the notifier function is the sndCall parameter that you specified when calling the OTConnect function. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_DATA


Normal data has arrived. Depending on the type of service of the endpoint you are using, you can call the OTRcvUData function or the OTRcv function to read it. Continue reading data until the function returns with the kOTNoDataErr result; you will not get another indication that data has arrived until you have read all the data and got this error.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_EXDATA


Expedited data has arrived. Use the OTRcv function to read it. Continue reading data by calling the OTRcv function until the function returns with the kOTNoDataErr result; you will not get another indication that data has arrived until you have read all the data and got this error.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_DISCONNECT


A connection has been torn down or rejected. Use the OTRcvDisconnect function to clear the event.
If the event is used to signify that a connection has been terminated, the cookie parameter to the notifier is NULL.
If the event indicates a rejected connection request, the cookie parameter to the notification routine is the same as the sndCall parameter that you passed to the OTConnect function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_ERROR


Obsolete.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_UDERR


The provider was not able to send the data you specified using the OTSndUData function even though the function returned successfully. You must call the OTRcvUDErr function to clear this event and determine why the function failed.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_ORDREL


The remote client has called the OTSndOrderlyDisconnect function to initiate an orderly disconnect. You must call the OTRcvOrderlyDisconnect function to acknowledge receiving the event.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_GODATA


Flow-control restrictions have been lifted. You can now send normal data.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_GOEXDATA


Flow-control restrictions have been lifted. You can now send expedited data.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_REQUEST


A request has arrived. Depending on the type of service for the endpoint you are using, you can call the OTRcvRequest function or the OTRcvURequest function to receive it. You must continue to call the function until it returns with the kOTNoDataErr result. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_REPLY


A response to a request has arrived. Depending on the type of service of the endpoint you are using, you can call the OTRcvReply function or OTRcvUReply function to receive it. You must continue to call the function until it returns with the kOTNoDataErr result.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_PASSCON


When the OTAccept function completes, the endpoint provider passes this event to the endpoint receiving the connection (whether that endpoint is the same as or different from the endpoint that calls the OTAccept function). The cookie parameter contains the resRef parameter to the OTAccept function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_RESET


A connection-oriented endpoint has received a reset from the remote end and has flushed all unread and unsent data. This only occurs for some types of endpoints, and it generally leaves the endpoint in an unknown state.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kPRIVATEEVENT


Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kCOMPLETEEVENT


Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_BINDCOMPLETE


The OTBind function has completed. The cookie parameter contains the retAddr parameter of the bind call.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_UNBINDCOMPLETE


The OTUnbind function has completed. The cookie parameter is meaningless.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_ACCEPTCOMPLETE


The OTAccept function has completed. The cookie parameter contains the resRef parameter to the OTAccept function. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_REPLYCOMPLETE


The OTSndUReply or OTSndReply functions have completed. The cookie parameter contains the sequence number used in the OTSndUReply or OTSndReply call. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_DISCONNECTCOMPLETE


The OTSndDisconnect function has completed. The cookie parameter contains the call parameter of the OTSndDisconnect function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_OPTMGMTCOMPLETE


The OTOptionManagement function has completed. The cookie parameter contains the ret parameter that you passed to the function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_OPENCOMPLETE


An asynchronous call to open a provider has completed. The cookie parameter contains the provider reference.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_GETPROTADDRCOMPLETE


The OTGetProtAddress function has completed. The cookie parameter contains the peerAddr parameter that you passed to the OTGetProtocolAddress function. If you passed NULL for that parameter, the cookie parameter contains the address passed in the boundAddr parameter.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_RESOLVEADDRCOMPLETE


The OTResolveAddress function has completed. The cookie parameter contains the retAddr parameter of the OTResolveAddress function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_GETINFOCOMPLETE


The OTGetEndpointInfo function has completed. The cookie parameter contains the info parameter of the OTGetEndpointInfo function.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_SYNCCOMPLETE


The OTSync function has completed. The cookie parameter is meaningless.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_MEMORYRELEASED


You are using an asynchronous endpoint that acknowledges sends and Open Transport is done using the buffers containing the data you are sending. If you called the OTSnd function, the cookie parameter contains the buf parameter. If you called the OTSndUData function, the cookie parameter contains the udata parameter. The result parameter contains the number of bytes that were sent. This might be less than the number you meant to send due to flow-control or memory restrictions.
You should not wait for the T_MEMORYRELEASED event from a previous send operation to trigger more sends. The exact time this event occurs depends on how the underlying provider is implemented. It might hold on to memory until the next send occurs, or behave in some other way which causes it to delay releasing memory.
Note that T_MEMORYRELEASED events can reenter your notifier. See OTAckSendsfor more information.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_REGNAMECOMPLETE


The OTRegisterName function has completed. The cookie parameter is the reply parameter, unless it was NULL. In this case, it is the req parameter.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_DELNAMECOMPLETE


The OTDeleteName function or the OTDeleteNameByID function has completed. The cookie parameter contains the name parameter or the nameId parameter of the function, respectively. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_LKUPNAMECOMPLETE


The OTLookupName function has completed. The cookie parameter contains the reply parameter of the OTLookUpName function.
Available in Mac OS X v10.0 and later.

kOTProviderIsDisconnected


Your provider was bound with a qlen parameter value greater than 0 and it has been disconnected (is no longer listening). You receive this event after a port has accepted a request to temporarily yield ownership of a port to another provider, which causes this provider to be disconnected from the port in question. This currently only happens with serial ports, but could also happen with other connection-oriented drivers that have characteristics similar to serial ports. You get a kOTProviderIsReconnected message when the port reverts back to this provider’s ownership.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTProviderIsReconnected


Your provider has been reconnected, that is, the cause for its disconnection has been relieved.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTProviderWillClose


When you return from the notifier function, Open Transport will close the provider whose reference is contained in the cookie parameter. The result parameter contains a result code specifying the reason why the provider had to close. For example, the user may have decided to switch links using the TCP/IP or AppleTalk control panel. The result codes that can be returned are in the range –3280 through –3285; these are documented in “Open Transport Result Codes.”
You can only get this event at system task time. Consequently, you are allowed to set the endpoint to synchronous mode (from within the notifier function) and call functions synchronously before you return from the notifier, at which point the provider is closed. After this, any calls other than OTCloseProvider will fail with a kOTOutStateErr error.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTProviderIsClosed


The provider has closed. The reason for being closed can be found in the OTResult value passed to your notifier.  The reasons typically are kOTPortHasDiedErr, kOTPortWasEjectedErr, or kOTPortLostConnectionErr.  At this point, any calls other than OTCloseProvider will fail with a kOTOutStateErr error.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTPortDisabled


A port has gone off line, as when the user removes a PCMCIA card while the computer is running. The OTResult parameter specifies the reason, if known, and the cookie parameter provides the port reference of the port that went off line. A port going off line often results in providers getting kOTProviderIsClosed events. There is no guarantee in Open Transport as to which of these events will be received first.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTPortEnabled


A port that had previously been disabled is now reenabled, as when the user reinserts a previously removed PCMCIA card while the computer is running. The cookie parameter is the port reference of the port that is now enabled.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTPortOffline


The port is now offline.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTPortOnline


A request has been made to close or yield this port.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTClosePortRequest


You currently are using a provider that is using a port that some other application wants to use. The OTResult parameter is the reason for the request (normally kOTNoError or kOTUserRequestedErr), and the cookie parameter is a pointer to an OTPortCloseStruct structure. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTYieldPortRequest


Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


kOTNewPortRegistered


A new port has been registered with Open Transport, as when the user inserts a new PCMCIA card. The cookie parameter is the port reference of the new port. Your provider receives this event the first time a new port is enabled. Subsequently, if a port is reenabled after being disabled, you receive the kOTPortEnabled event instead.

Constants


T_MORE


There is more data for the current TSDU or ETSDU. The next send or receive operation will handle additional data for this TSDU or ETSDU.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_EXPEDITED


On sends, the data is sent as expedited data if the endpoint supports expedited data. On receives, the flag indicates that expedited data was sent.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_ACKNOWLEDGED


The transaction must be acknowledged before the send or receive function can complete.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_PARTIALDATA


There is more data for the current TSDU or ETSDU. Unlike T_MORE, T_PARTIALDATA does not guarantee that the next send or receive operation will handle additional data for this TSDU or ETSDU.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_NORECEIPT


There is no need to send a T_REPLY_COMPLETE event to complete the transaction. If you don’t need to know when the transaction is actually done, you can set this flag to improve performance.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_TIMEDOUT


The reply timed out. If a protocol such as ATP loses the acknowledgment for a transaction that needs to be acknowledged, the transaction will eventually time out. Since the reply didn’t really fail (it just timed out), Open Transport can send a T_REPLY_COMPLETE event to complete the transaction and set this flag to explain what happened.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_NEGOTIATE


Negotiate the option values specified in the opt.buf field of the req parameter.
The overall result of the negotiation is specified by the flags field of the ret parameter. The opt.buf field of the ret parameter points to a buffer where negotiated values for each option are placed.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_CHECK


Verify whether the endpoint supports the options referenced by the opt.buf field of the req parameter. The overall result of the verification is specified by the flags field of the ret parameter. Specific verification results are returned in the opt.buf field of the ret parameter.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_DEFAULT


Retrieve the default value for those options in the buffer referenced by the req->opt.buf field. To retrieve default values for all the options supported by an endpoint, include just the option T_ALLOPT in the options buffer.Option values are returned in the opt.buf field of the ret parameter.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


T_CURRENT


Retrieve the current value for those options that the endpoint supports and that are specified in the buffer referenced by the req->opt.buf field. To retrieve current values for all the options that an endpoint supports, include just the option T_ALLOPT in the options buffer.Option values are returned in the opt.buf field of the ret parameter.
Available in Mac OS X v10.0 and later.

   OPT_KEEPALIVE = 0x0008
};



Constants


XTI_DEBUG


A 32 bit constant specifying whether debugging is enabled. Debugging is disabled if the option is specified with no value. This option is an absolute requirement.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_LINGER


A value defined by a linger structure (page 571) that specifies whether the option is turned on (T_YES) or off (T_NO) and specifies a linger period in seconds. This option is an absolute requirement; however, you do not have to specify a value for the l_linger field of the linger structure.
You use this option to extend the execution of the OTCloseProvider function for some specified amount of time. The delay allows data still queued in the endpoint’s internal send buffer to be sent before the endpoint provider is closed. If you call the OTCloseProvider function and the send buffer is not empty, the endpoint provider attempts to send the remaining data during the linger period, before closing. Open Transport discards any data remaining in the send buffer after the linger period has elapsed.
Consult the documentation for your protocol to determine the valid range of values for the linger period.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_RCVBUF


A 32-bit integer specifying the size of the endpoint’s internal buffer allocated for receiving data. You can increase the size of this buffer for high-volume connections or decrease the buffer to limit the possible backlog of incoming data.
This option is not an absolute requirement. Consult the documentation for your protocol to determine the valid range of values for the buffer size.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_RCVLOWAT


A 32-bit integer specifying the low-water mark for the receive buffer—that is, the number of bytes that must accumulate in the endpoint’s internal receive buffer before you are advised that data has arrived via a T_DATA event. Choosing a value that is too low might result in your application’s getting an excessive number of T_DATA events and doing unnecessary reads. Choosing a value that is too high might result in Open Transport running out of memory and disabling incoming data packets.
This option is not an absolute requirement. Consult the documentation for your protocol to determine the valid range of values for the low-water mark.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_SNDBUF


A 32-bit integer specifying the size of the endpoint’s internal buffer allocated for sending data. Specifying a value that is too low might result in Open Transport doing more sends than necessary and wasting processor time; specifying a value that is too high might cause flow control problems.
This option is not an absolute requirement. Consult the documentation for your protocol to determine the valid range of values for the buffer size.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_SNDLOWAT


A 32-bit integer specifying the low-water mark for the send buffer—that is, the number of bytes that must accumulate in the endpoint’s internal send buffer before Open Transport actually sends the data. Choosing a value that is too low might result in Open Transport’s doing too many sends and wasting processor time. Choosing a value that is too high might result in flow control problems. A value that is slightly lower than the largest packet size defined for the endpoint is a good choice.
This option is not an absolute requirement. Consult the documentation for your protocol to determine the valid range of values for the low-water mark.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


XTI_PROTOTYPE


The protocol type used by the endpoint. The option is supported by the RawIP endpoint.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_CHECKSUM


A 32-bit constant specifying whether checksums are performed. Specify 1 to turn the option on and 0 to turn it off. If you turn it on, a checksum is calculated when a packet is sent and recalculated when the packet is received. If the checksum values match, the client receiving the packet can be fairly certain that data has not been corrupted or lost during transmission. If the checksum values don’t match, the receiver discards the packet.
This option is usually implemented by the lowest-level protocol, although you might be allowed to set it at a higher level. For example, if you use an ATP endpoint, you can set checksumming at the ATP level, even though it is implemented by the underlying DDP protocol.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_RETRYCNT


A 32-bit integer specifying the number of times a function can attempt packet delivery before returning with an error. A value of 0 means that the function should attempt packet delivery an infinite number of times.
This option is usually implemented by connection-oriented endpoints or connectionless transaction-based endpoints to enable reliable delivery of data. Such protocols normally set a default value for this option.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_INTERVAL


A 32-bit integer specifying the interval of time in milliseconds that should elapse between attempts to deliver a packet. The number of attempts is defined by the OPT_RETRYCNT option. 
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_ENABLEEOM


An 32-bit integer specifying end-of-message capability. If you set this option, you enable the use of the T_MORE flag with the OTSnd function to mark the end of a logical unit. This option has meaning only for connection-oriented protocols. A value of 0 clears the option; a value of 1 sets it.
This option is not association-related.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_SELFSEND


A 32-bit integer allowing you to send broadcast packets to yourself. A value of 0 clears the option; a value of 1 sets it.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_SERVERSTATUS


A string that sets the server’s status. The maximum length is protocol dependent. For more information, consult the documentation for the protocol you are using.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_ALERTENABLE


A keepalive structure that specifies whether “keep alive” is turned on (T_YES) or off (T_NO) and specifies the timeout period in minutes.
Connection-oriented protocols can use this option to check that the connection is maintained. If a connection is established but there is no data being transferred, you can specify a time limit within which Open Transport checks to see that the remote end of the connection is still alive. If it is not, Open Transport tears down the connection.
This option is association-related.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


OPT_KEEPALIVE


Enables or disables protocol alerts.
Available in Mac OS X v10.0 and later.
Declared in OpenTransport.h.


Discussion


Open Transport defines XTI-level options. These options are not association-related. If the protocol you are using supports these options, you can negotiate them while the endpoint is in any state. The protocol level for all of these options is XTI_GENERIC.


Open Transport also defines some generic options that you can use with any protocol that supports them, listed in this enumeration starting with OPT_CHECKSUM. The protocol level for each of these options is the same as the name of the protocol that supports them.
