PHONE_DEVSPECIFIC (TSPI) (Compact 2013)

  • Article

3/26/2014

This message is sent to the PHONEEVENT callback function to notify TAPI about device-specific events occurring at the phone. The meaning of the message and the interpretation of the parameters is implementation defined.

Syntax

PHONE_DEVSPECIFIC
    htPhone = (HTAPIPHONE) hPhoneDevice;
    dwMsg = (DWORD) PHONE_DEVSPECIFIC;
    dwParam1 = (DWORD) DeviceData1;
    dwParam2 = (DWORD) DeviceData2;
    dwParam3 = (DWORD) DeviceData3;

Parameters

  • htPhone
    The TAPI opaque object handle to the phone device.
  • dwMsg
    The value PHONE_DEVSPECIFIC.
  • dwParam1
    Device specific.
  • dwParam2
    Device specific.
  • dwParam3
    Device specific.

Remarks

TAPI sends the PHONE_DEVSPECIFIC message to applications in response to receiving this message from a service provider. The htPhone is translated to the appropriate hPhone as the hDevice parameter at the TAPI level. The dwParam1, dwParam2, and dwParam3 parameters are passed through unmodified.
