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.
