LINE_REQUEST hDevice = (DWORD) 0; dwCallbackInstance = (DWORD) hRegistration; dwParam1 = (DWORD) RequestMode; dwParam2 = (DWORD) RequestModeDetail1; dwParam3 = (DWORD) RequestModeDetail2;
No return value.
The LINE_REQUEST message is sent to the highest priority application that has registered for the corresponding request mode. This message indicates the arrival of an Assisted Telephony request of the specified request mode. If dwParam1 is LINEREQUESTMODE_MAKECALL or LINEREQUESTMODE_MEDIACALL, the application can invoke lineGetRequest using the corresponding request mode to receive the request. If dwParam1 is LINEREQUESTMODE_DROP, the message contains all of the information the request recipient needs to perform the request.
