Linux 2.6 - man page for raise (linux section 3posix)

RAISE(P)			    POSIX Programmer's Manual				 RAISE(P)

NAME
       raise - send a signal to the executing process

SYNOPSIS
       #include <signal.h>

       int raise(int sig);

DESCRIPTION
       The  raise() function shall send the signal sig to the executing    thread or process.  If
       a signal handler is called, the raise() function shall not return until after  the  signal
       handler does.

       If  the	implementation	supports  the  Threads option, the effect of the raise() function
       shall be equivalent to calling:

	      pthread_kill(pthread_self(), sig);

       Otherwise, the effect of the raise() function shall be equivalent to calling:

	      kill(getpid(), sig);

RETURN VALUE
       Upon successful completion, 0 shall be returned. Otherwise,  a  non-zero  value	shall  be
       returned    and errno shall be set to indicate the error.

ERRORS
       The raise() function shall fail if:

       EINVAL The value of the sig argument is an invalid signal number.
