Andrew,

Thanks. I am using Real Time Signals now (24 to 31 only) and things are
working fine.

Is this other thread also a posix thread?

It is probably worth single stepping through kill() to see what it
does. That might give you a clue as to why your code is not working.

[ECOS] POSIX Signals

[Ali, Khurram]

Hi,

In my application, I am using signal numbered 18 to 31. Is that allowed?

I send a signal 31 using kill(0, 31). My signal 31 has an action handler
that gets called. I then call sigwait from another thread with 31 added
to sigset_t. However, sigwait does not return. If I call kill and
sigwait from the same thread, things work okay.

Am I doing something wrong or am I missing something?

Thank you,
Khurram
