TSPI_lineMSPIdentify function (tspi.h)
The TSPI_lineMSPIdentify function determines the associated MSP CLSID for every line. This function requires TAPI 3.0 version negotiation.
Syntax
LONG TSPIAPI TSPI_lineMSPIdentify(
DWORD dwDeviceID,
GUID *pCLSID
);
Parameters
dwDeviceID
The line device whose CLSID is requested.
pCLSID
The TSP fills in the CLSID of the MSP to be created for the line device indicated in dwDeviceID.
Return value
Returns zero if the function succeeds, or an error number if an error occurs. Possible return values are as follows:
Remarks
Note that TAPI 3 calls TSPI_lineMSPIdentify only if the LINEDEVCAPFLAGS_MSP flag is set in the TSP. (You can set LINEDEVCAPFLAGS_constants in the dwDevCapFlags member of the LINEDEVCAPS structure.)
If the device does not have an associated MSP, the TSP returns LINEERR_OPERATIONUNAVAIL.
