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 non-zero for failure.

CONFORMING TO
       C89, C99, POSIX.1-2001.
