RAISE(3P)                 POSIX Programmer's Manual                RAISE(3P)

PROLOG         top

       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         top

       raise — send a signal to the executing process

SYNOPSIS         top

       #include <signal.h>

       int raise(int sig);

DESCRIPTION         top

       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         top

       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         top

       The raise() function shall fail if:

       EINVAL The value of the sig argument is an invalid signal number.

       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

       None.

RATIONALE         top

       The term ``thread'' is an extension to the ISO C standard.

FUTURE DIRECTIONS         top

       None.
