Hi,
I have a small program shown below:
[ ... ]
This should print k = 24,0,0 and
then the thread should again go into wait. But instead the program gets
the signal 24 and is stopped(basically, it executes the default signal
handler of SIGTSTP).
This program works fine on other platforms like HP, AIX and Linux.
Can anyone tell me why this is not working on solaris?
See sigwait(2):
NOTES
The sigwait() function cannot be used to wait for signals
that cannot be caught (see sigaction(2)). This restriction
is silently imposed by the system.
See sigaction(2):
ERRORS
The sigaction() function will fail if:
EINVAL The value of the sig argument is not a valid sig-
nal number or is equal to SIGKILL or SIGSTOP. In
addition, if in a multithreaded process, it is
equal to SIGWAITING, SIGCANCEL, or SIGLWP.
In short, you cannot catch SIGSTOP.
No, I don't know why/whether it works on other platforms.

Thanks
