The TLookupBuffer Structure

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. Figure 6-1 shows the structure of the reply buffer.

The TLookupBuffer structure is defined by the TLookupBuffer data type.

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

Field descriptions

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.
