RAISE(3)

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 non-zero for failure.

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