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

       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.

       pthread_kill — send a signal to a thread

       #include <signal.h>

       int pthread_kill(pthread_t thread, int sig);

       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.

       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.

       The pthread_kill() function shall fail if:

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

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

       The following sections are informative.


       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 sig‐
       nal 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.

       If an implementation detects use of a thread ID after the  end  of  its
       lifetime, it is recommended that the function should fail and report an
       [ESRCH] error.
