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

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
       pthread_kill - send a signal to a thread

SYNOPSIS
       #include <signal.h>

       int pthread_kill(pthread_t thread, int sig);

DESCRIPTION
       The pthread_kill() function shall request that a signal be delivered to the specified thread.

       As in kill(), if sig is zero, error checking shall be performed but no signal shall actually be sent.

RETURN VALUE
       Upon successful completion, the function shall return a value of zero.  Otherwise, the function	shall  return  an  error  number.  If  the
       pthread_kill() function fails, no signal shall be sent.

ERRORS
       The pthread_kill() function shall fail if:

       ESRCH  No thread could be found corresponding to that specified by the given thread ID.

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

       The pthread_kill() function shall not return an error code of [EINTR].

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       The  pthread_kill()  function  provides a mechanism for asynchronously directing a signal at a thread in the calling process. This could be
       used, for example, by one thread to affect broadcast delivery of a signal to a set of threads.

       Note that pthread_kill() only causes the signal to be handled in the context of the given thread; the signal action (termination  or  stop-
       ping) affects the process as a whole.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
