RAISE(3P) POSIX Programmer's Manual RAISE(3P)
PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAME
raise -- send a signal to the executing process
SYNOPSIS
#include <signal.h>
int raise(int sig);
DESCRIPTION
The functionality described on this reference page is aligned with the
ISO C standard. Any conflict between the requirements described here
and the ISO C standard is unintentional. This volume of POSIX.1-2008
defers to the ISO C standard.
The raise() function shall send the signal sig to the executing thread
or process. If a signal handler is called, the raise() function shall
not return until after the signal handler does.
The effect of the raise() function shall be equivalent to calling:
pthread_kill(pthread_self(), sig);
RETURN VALUE
Upon successful completion, 0 shall be returned. Otherwise, a non-zero
value shall be returned and errno shall be set to indicate the error.
ERRORS
The raise() function shall fail if:
EINVAL The value of the sig argument is an invalid signal number.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
The term ``thread'' is an extension to the ISO C standard.
FUTURE DIRECTIONS
None.
