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

Parameters

  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

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.
