lpLineDevCaps A pointer to a variably sized structure of type LINEDEVCAPS. Upon successful completion of the request, this structure gets filled with line device capabilities information. Prior to calling lineGetDevCaps, the application should set the dwTotalSize member of this structure to indicate the amount of memory that is available to TAPI for returning information. lineGetID The lineGetID function returns a device identifier for the specified device class that is associated with the selected line, address, or call. Function Details LONG lineGetID( HLINE hLine, DWORD dwAddressID, HCALL hCall, DWORD dwSelect, LPVARSTRING lpDeviceID, LPCSTR lpszDeviceClass ); Parameters hLine A handle to an open line device. dwAddressID An address on the given open line device. hCall A handle to a call. dwSelect Specifies whether the requested device identifier is associated with the line, address or a single call. The dwSelect parameter can only have a single flag set. This parameter uses the following LINECALLSELECT_constants: • LINECALLSELECT_LINE Selects the specified line device. The hLine parameter must be a valid line handle; hCall and dwAddressID are ignored. • LINECALLSELECT_ADDRESS Selects the specified address on the line. Both hLine and dwAddressID must be valid; hCall is ignored. • LINECALLSELECT_CALL Selects the specified call. hCall must be valid; hLine and dwAddressID are both ignored. lpDeviceID A pointer to a memory location of type VARSTRING, where the device identifier is returned. Upon successful completion of the request, the device identifier fills this location. The format of the returned information depends on the method that the device class API uses for naming devices.
