This message is sent to an application to report the results of function call that completed asynchronously.

Syntax

PHONE_REPLY
    hPhone = (HPHONE) 0;
    dwCallbackInstance = (DWORD) hCallback;
    dwParam1 = (DWORD) idRequest;
    dwParam2 = (DWORD) Status;
    dwParam3 = (DWORD) 0;

Parameters

  • hPhone
    Not used by this message. Value is NULL.
  • dwCallbackInstance
    Value that returns the application's callback instance.
  • dwParam1
    Request identifier for which this is the reply.
  • dwParam2
    Success or error indication. The application should cast this parameter into a LONG. Zero indicates success; a negative number indicates an error.
  • dwParam3
    Not used by this message. Value is NULL.

Return Value

None.

Remarks

Functions that operate asynchronously return a positive request identifier value to the application. This request identifier is returned with the reply message to identify the request that was completed. The other parameter for the PHONE_REPLY message carries the success or failure indication. Possible errors are the same as those defined by the corresponding function. This message cannot be disabled.

Requirements
