What is GUID in TAPI?

[Mohit]

Hi friends,

Can any one tell me what is this GUID used in the TAPI.
Actually, I had found it in the LinePermanentGuid and ProtocolGuid
parameters of LINDEVCAPS structure.

Thanks,
Mohit

Mohit,
please see MSDN, TAPI.H and TAPI3.H for details:

PermanentLineGuid
GUID permanently associated with the line device.

ProtocolGuid
Current TAPI protocol. This member of the structure is available only if the
negotiated TAPI version is 3.0 or higher. The protocols are declared in
tapi3.h.

typedef struct _GUID
{
unsigned long Data1;
unsigned short Data2;
unsigned short Data3;
unsigned char Data4[8];
} GUID;

#if (TAPI_CURRENT_VERSION >= 0x00020002)
GUID PermanentLineGuid; // TAPI v2.2
#endif

#if (TAPI_CURRENT_VERSION >= 0x00030000)
DWORD dwAddressTypes; // TAPI v3.0
GUID ProtocolGuid; // TAPI v3.0
DWORD dwAvailableTracking; // TAPI v3.0
#endif

const BSTR TAPIPROTOCOL_String_PSTN =
L"{831CE2D6-83B5-11D1-BB5C-00C04FB6809F}";

const BSTR TAPIPROTOCOL_String_H323 =
L"{831CE2D7-83B5-11D1-BB5C-00C04FB6809F}";

const BSTR TAPIPROTOCOL_String_Multicast =
L"{831CE2D8-83B5-11D1-BB5C-00C04FB6809F}";
