PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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 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.

       If the implementation supports the Threads option, the effect of the raise() function shall be equivalent to calling:

	      pthread_kill(pthread_self(), sig);

       Otherwise, the effect of the raise() function shall be equivalent to calling:

	      kill(getpid(), 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.

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.

       None.
