Is the line: " const int minut_1 = -1;"
Just a typo or is it in fact passing a different value for minus_1? I'm guessing the former, as I would have thought you would get a compiler error.

That is, if it is invoked from a UNIX shell, it will close all the open file descriptors, do a setsid to put itself into its own, unique, process group, and do the "double fork()" which I read about in a advance UNIX programming book. If I run this program using TSO OMVS or a standard telnet connection to a UNIX prompt, everything works well. But if I logon via an ssh tunnel to a UNIX prompt, the code to close all descriptors: const int zero = 0; const int minut_1 = -1; ... rc = fcntl(zero, F_CLOSFD, minus_1); Will return with rc == -1 (error), an errno value of 139 (EPERM) and a errnojr value of 0x0B28E128. Looking this up with bpxmtext only says: BPXPRIPK 07/18/08 There is a hit on this, but for HBB7780. I'm on HBB7770 (z/OS 1.12). There are no messages on the z/OS SYSLOG. Any ideas? I can just ignore the -1 return code but I really, really, really don't like doing that. -- Wasn't there something about a PASCAL programmer knowing the value of everything and the Wirth of nothing?
