This message is sent to the LINEEVENTcallback function to notify TAPI about device-specific events occurring on a line or address. The meaning of the message and the interpretation of the dwParam1 through dwParam3 parameters is device specific.

htLine = (HTAPILINE) 
hLineDevice;

htCall = (HTAPICALL) 0;

dwMsg = (DWORD) LINE_DEVSPECIFIC;

dwParam1 = (DWORD) 
DeviceData1;

dwParam2 = (DWORD) 
DeviceData2;

dwParam3 = (DWORD) 
DeviceData3;

Parameters

htCall

dwMsg

The value LINE_DEVSPECIFIC.

dwParam1

Device specific.

dwParam2

Remarks

This message is used by a service provider in conjunction with the TSPI_lineDevSpecificfunction. Its meaning is device specific.

TAPI sends the LINE_DEVSPECIFIC message to applications in response to receiving this message from a service provider. The htLineis translated to the appropriate hLineas the hDeviceparameter at the TAPI level. The dwParam1, dwParam2, and dwParam3parameters are passed through unmodified.

This differs from the corresponding message at the TAPI level in that it is used only to report device-specific events occurring on a line or address.
