Consult your system's sigaction manpage for details +, see also POSIX::SigRt. ... The following are also defined by POSIX/SUSv3, but unfortunately not v +ery widely implemented: pid the process id generating the signal uid the uid of the process id generating the signal status exit value or signal for SIGCHLD band band event for SIGPOLL
