NAME

       raise - send a signal to the caller

SYNOPSIS

       #include <signal.h>

       int raise(int sig);

DESCRIPTION

       The raise() function sends a signal to the calling process or thread.  In a single-threaded program it is equivalent to

	   kill(getpid(), sig);

       In a multithreaded program it is equivalent to

	   pthread_kill(pthread_self(), sig);

       If the signal causes a handler to be called, raise() will only return after the signal handler has returned.

RETURN VALUE

       raise() returns 0 on success, and nonzero for failure.

CONFORMING TO

       C89, C99, POSIX.1-2001.
