Platform SDK: TAPI |
The lineGetMessage function returns the next TAPI message that is queued for delivery to an application that is using the Event Handle notification mechanism (see lineInitializeEx for further details).
LONG WINAPI lineGetMessage( HLINEAPP hLineApp, LPLINEMESSAGE lpMessage, DWORD dwTimeout );
Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:
LINEERR_INVALAPPHANDLE, LINEERR_OPERATIONFAILED, LINEERR_INVALPOINTER, LINEERR_NOMEM.
If the lineGetMessage function has been called with a non-zero timeout and the application calls lineShutdown on another thread, this function returns immediately with LINEERR_INVALAPPHANDLE.
If the timeout expires (or was zero) and no message could be fetched from the queue, the function returns with the error LINEERR_OPERATIONFAILED.
