PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       raise - send a signal to the executing process
13

SYNOPSIS

15       #include <signal.h>
16
17       int raise(int sig);
18
19

DESCRIPTION

21       The raise() function shall send the signal sig to the executing  thread
22       or  process.  If a signal handler is called, the raise() function shall
23       not return until after the signal handler does.
24
25       If the implementation supports the Threads option, the  effect  of  the
26       raise() function shall be equivalent to calling:
27
28
29              pthread_kill(pthread_self(), sig);
30
31       Otherwise,  the  effect  of the raise() function shall be equivalent to
32       calling:
33
34
35              kill(getpid(), sig);
36

RETURN VALUE

38       Upon successful completion, 0 shall be returned. Otherwise, a  non-zero
39       value shall be returned  and errno shall be set to indicate the error.
40

ERRORS

42       The raise() function shall fail if:
43
44       EINVAL The value of the sig argument is an invalid signal number.
