Paul,
I've never done this with C (and don't know anything about C), but I have
done similar functions with RPGLE.
When you create your C programs with CRTPGM, be sure to specify *CALLER for
the Activation Group. This will maintain the MQ handles between invocations
because all the programs will run in the same activation group. Also, when
I do this with RPGLE, I make sure that the "utility" programs end with a
"return" as opposed to a hard end. This keeps everything open. I guess
there is an analogous method in C.

Subject: RPG/400, C and MQ
Hi all,
I know almost nothing about RPG but have to find out the feasability of
something.
Can an RPG/400 program call an ILE C program to do the MQ Conn and Open,
and
then call another C program to do the MQPuts?
I.e. something like the following:
RPG/400 Program
|
V
Call ILE C program to Connect to QMgr, Open Queue etc
|
V
Back to main RPG program
|
V
Call ILE C program to Put messages to a queue
|
V
Back to main RPG program
|
etc
My main concern is whether the Connection and Object handles will remain
valid
across multpile invocations of the C program. Of course a small sample of
code
would be beyond my wildest dreams ;-)
Cheers,
Paul
