NAME
       thr_kill - send a signal to a thread

SYNOPSIS
       cc -mt [ flag... ] file... [ library... ]
       #include <signal.h>
       #include <thread.h>

       int thr_kill(thread_t thread, int sig);

DESCRIPTION
       The  thr_kill()	function sends the sig signal to the thread designated
       by thread. The thread argument must be a member of the same process  as
       the  calling thread. The sig argument must be one of the signals listed
       in signal.h(3HEAD), with the exception of SIGCANCEL being reserved  and
       off limits to thr_kill(). If sig is 0, a validity check is done for the
       existence of the target thread; no signal is sent.

RETURN VALUES
       Upon successful completion, thr_kill() returns 0. Otherwise,  an	 error
       number is returned. In the event of failure, no signal is sent.

ERRORS
       The thr_kill() function will fail if:

       EINVAL
		 The  sig  argument  value is not zero and is an invalid or an
		 unsupported signal number.

       ESRCH
		 No thread was found that corresponded to  the	thread	desig‐
		 nated by thread ID.
