Weird problem w/semaphores

[Tom Daly <Tdaly@xxxxxxxxxxxxxx>]

This is strange.

I'm calling CEEMOUT api from RPG to log messages in the joblog.  I'm also
calling sem_open api to create a named semaphore.  It appears that once
CEEMOUT has been called in the program all subsequent calls to sem_open
fail.  The sem_open must be prior to any call to CEEMOUT.

Anyone have any ideas?

TIA,
Tom

 |  Paul,
 |
 |  Thanks for the tip!  Using a named semaphore is working
 |  well in my test pgm.
 |  The next hurdle is to understand why sem_open fails in the
 |  real application,
 |  which is a spawned pgm.  I don't know if the spawning is
 |  doing something
 |  fishy  (sorry - couldn't resist!)

 |   |   |  Hi Tom,
 |   |   |
 |   |   |  As far as the waiting is concerned... you could use
 |   |   |  semaphores instead of
 |   |   |  the usrspc byte.
 |   |   |
 |   |   |  Kind regards,
 |   |   |  Paul
