NAME

6       raise - send a signal to the caller
7

SYNOPSIS

9       #include <signal.h>
10
11       int raise(int sig);
12

DESCRIPTION

14       The  raise()  function sends a signal to the calling process or thread.
15       In a single-threaded program it is equivalent to
16
17           kill(getpid(), sig);
18
19       In a multithreaded program it is equivalent to
20
21           pthread_kill(pthread_self(), sig);
22
23       If the signal causes a handler to be called, raise() will  only  return
24       after the signal handler has returned.
25

RETURN VALUE

27       raise() returns 0 on success, and non-zero for failure.
28
