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.
