Scans T-Server for one or more incoming messages for a time interval specified by the parameter timeout. This function does not affect delivery of pending messages and does not process timers, so it should not be used with connections opened in asynchronous mode or if ADDP protocol is used. (Use TScanServerEx() to process timers.)
|server||Local server handle to the T-Server in question.|
|timeout||Time interval, in seconds, during which a message from T-Server will be sought.|
>0 — Number of received messages.
0 — The timeout is expired.
-1 — Error condition. Returned to the application if the request has not been processed due to an incorrect function statement.
