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 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.
