Regarding to what Guy Keren wrote:
I saw that sigqueue function is documented (xman) on RH 7.1;
so maybe it is present on the system -- I will check it tomorow (no,
today-it's past 24).
If it is so, than Guy Keren affirmation "nor posix semaphores in the kernel"
it's not
holding ground. Can it be that just some of Posix functionality exist on RH
7.1 ?
That's not making much sense...
How can a system be Posix compliant but without Posix ipc?
