[9fans] ape buglet (maybe)

[steve.simon]

Hi,

I have come widely used code I'am trying to port (imake) which relies on
wait(2) [IE ape's wait] returning -1 if the current process has no children.

I can fix this easily in the application but I think the bug is in ape.

I cannot find a definitive answer on the net; so anyone got a copy of the POSIX
documents to hand?

-Steve

Strange; it took me about 5 seconds to locate the wait(2)
manual page for Open Unix 8.0 from the Caldera Web site:

"If wait returns due to a stopped or terminated child process,
the process ID of the child is returned to the calling process.
Otherwise, wait returns -1 and sets errno to identify the error."

"ECHILD: The calling process has no existing unwaited-for child
processes."
