  • Article

3/26/2014

This message is sent to the LINEEVENT callback function when the call information about the specified call has changed. TAPI can invoke TSPI_lineGetCallInfo to determine the current call information.

Syntax

LINE_CALLINFO
    htLine = (HTAPILINE) hLineDevice;
    htCall = (HTAPICALL) hCallDevice;
    dwMsg = (DWORD) LINE_CALLINFO;
    dwParam1 = (DWORD) CallInfoState;
    dwParam2 = (DWORD) 0;
    dwParam3 = (DWORD) 0;

Parameters

  • htLine
    The TAPI opaque object handle to the line device.
  • htCall
    The TAPI opaque object handle to the call device.
  • dwMsg
    The value LINE_CALLINFO.
  • dwParam1
    Specifies the call information item that has changed. This parameter can be a combination of the LINECALLINFOSTATE_ constants.
  • dwParam2
    Not used.
  • dwParam3
    Not used.

Remarks

This message is sent to TAPI whenever the event occurs and TAPI has the line open. However, no LINE_CALLINFO messages are sent for a call after the call has entered the idle state.
