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.
