Yes, zero is a valid descriptor number.Yes, each job (assuming you mean "job" as in a unit of work on i5/OS) should have a separate pool of descriptors. So every job on the system can have a "socket 0", and they won't conflict with one another.

Okay, time for a sockets newbie question. I have multiple jobs executing the same program. This program uses the various sockets a.p.i.s to establish a connect to a remote server. I noticed that the socket a.p.i. returned a 0 in two of the jobs. It seems to me each job should have a different value returned from socket, but I don't really know. It seems like 0 is a valid value since anything less than 0 is considered an error. So I'm wondering whether anyone can confirm that 0 is a valid value and whether different jobs should have different socket i.d.s.
