i had a doubt about signal delivery under LINUX. assume that a
process sends a signal to itself using the kill() or sigsend() call.
is it guaranteed that the signal will be delivered and handled before the
kill()/sigsend() call itself returns ? is this OS dependent or is the
behaviour specified by any standard (POSIX ?).
also is the sigsend() call POSIX ? it exists on solaris/dunix/hpux
but not on linux. its also doesn't seem to be present in glibc.
cheers,
yadav
