+<h3>SIGACTION(2) Linux Programmer's Manual SIGACTION(2)
+</h3>
+
+<h3>NAME
+</h3> signal - ANSI C signal handling.
+
+
+<h3>SYNOPSIS
+</h3> #include &lt;signal.h&gt;
+
+
+ void (*signal(int signum, void (*handler)(int)))(int);
+
+
+<h3>DESCRIPTION
+</h3> The signal system call installs a new signal handler for
+ signal signum. The signal handler is set to handler which
+ may be a user specified function, or one of the following:
+
+ SIG_IGN
+ Ignore the signal.
+
+ SIG_DFL
+ Reset the signal to its default behavior.
+
+
+
+<h3>RETURN VALUE
+</h3> signal returns the previous value of the signal handler,
+ or SIG_ERR on error.
+
+
+<h3>NOTES
+</h3> Signal handlers cannot be set for SIGKILL or SIGSTOP.
+
+ Unlike BSD systems, signals under Linux are reset to their
+ default behavior when raised.
+
+ If you're confused by the prototype at the top of this
+ manpage, it may help to see it separated out thus:
+
+ typedef void (*sighandler_t)(int);
+ sighandler_t signal(int signum, sighandler_t handler);
