SAS/CONNECT User's Guide

Query a Connection Object

The event types returned by the _query method are CONNECT, MESSAGE, DISCONNECT, and ABORT.

If a CONNECT event is returned from the _query method, it means that a client application has initiated a connect so that it can communicate with the server application. The server application can then use the returned connection_object parameter for subsequent queries from that specific user.

call send(connection_object, '_query', eventtype, 
          msgtype, attach_list, rc);

If a MESSAGE event is returned by the _query method, the server receives the MESSAGE and responds.

If a DISCONNECT event is returned by the _query method, the specific client application has terminated the connection and the connection object is deleted.
