Use sigaction instead of signal.
From signal man page : "The behavior of signal() varies across Unix versions, and has also varied historically across different versions of Linux. Avoid its use: use sigaction(2) instead. See Portability below." The code was taken from there : http://www.gnu.org/software/libtool/manual/libc/Sigaction-Function-Example.html Signed-off-by: Chantry Xavier <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
