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.
