Driver Services Information Structure

The DriverServiceInfo structure describes the category, type, and version of a driver's programming interface services.

struct DriverServiceInfo {
                     OSType serviceCategory;
                     OSType serviceType;
                     NumVersion serviceVersion;
                     };

typedef struct DriverServiceInfo DriverServiceInfo;

typedef struct DriverServiceInfo *DriverServiceInfoPtr;

enum {              /*used in serviceCategory*/
                     kServiceCategoryDisplay = 'disp', /*display*/
                     kServiceCategoryOpentransport = 'otan',/*Open
                       Transport*/
                     kServiceCategoryBlockstorage = 'blok', /*block
                       storage*/
                     kServiceCategorySCSISim = 'scsi', /*SCSI SIM*/
                     kServiceCategoryndrvdriver = 'ndrv' /*generic*/
                     };

Note

Current display devices use the generic device type 'ndrv'.

Field descriptions

serviceCategory: Specifies driver support services for given device family. The following device families are currently defined:
serviceType: Subcategory (meaningful only in a given service category).
serviceVersion: Version resource ('vers' ) used to specify the version of a set of services. It lets interfaces be modified over time.

Name	Supports services defined for
`'blok'`	block drivers family
`'disp'`	video display family
`'ndrv'`	generic native driver devices
`'otan'`	Open Transport
`'scsi'`	SCSI Interface Module
