Hi,

I'm just now beginning to play with operating systems. Here's my problem:

I'm calling an executable using a C system() call while setting the timeout
in the call using "ulimit -t". Everything times out exactly as expected
(user time), but the return value (after passing through WEXITSTATUS per the
man pages) is 137 instead of what I would expect - SIGXCPU (which happens to
have the value 24 or 25 - can't remember which right now). I've looked
everywhere for 137 - it doesn't match up with any of the signals (28 of
them) that I have in my book "Advanced UNIX Programming" (2nd Edition), nor
am I seeing anything in the manpages. What I mean by the "28 of them" is
that I looked at their actual values on the system I am using and none of
them is 137. So, does anyone have any insight or suggestions on this issue?

Thanks for you time,
Shane
