Syntax

CALL MSMQCLOSEQUEUE(hQueue, rc);

Arguments

hQueue

Numeric, input

Specifies the MSMQ handle to an open queue. This parameter is obtained from a previous MSMQOPENQUEUE function call.

rc

Numeric, output

Provides the return code from the CALL routine. If an error occurs, then the return code is nonzero. A return code of -1 reflects a SAS internal error. Otherwise, it represents an MSMQ error code. You can use the SAS function SYSMSG() to obtain a textual description of the return code.

Example

This example closes a queue.

length msg $ 200;
rc=0;
CALL MSMQCLOSEQUEUE(hQueue, rc);
if rc ^= 0 then do;
   put 'MSMQCloseQueue: failed';
   msg = sysmsg();
   put msg;
end;
else put 'MSMQCloseQueue: succeeded';
