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  return  only
24       after the signal handler has returned.
25

RETURN VALUE

27       raise() returns 0 on success, and nonzero for failure.

NOTES

42       Since version 2.3.3, glibc implements raise() by calling tgkill(2),  if
43       the kernel supports that system call.  Older glibc versions implemented
44       raise() using kill(2).
