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);

       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.

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

       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 designated by thread ID.
