NAME

SYNOPSIS

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

13       int thr_kill(thread_t thread, int sig);

DESCRIPTION

17       The  thr_kill()  function sends the sig signal to the thread designated
18       by thread. The thread argument must be a member of the same process  as
19       the  calling thread. The sig argument must be one of the signals listed
20       in signal.h(3HEAD), with the exception of SIGCANCEL being reserved  and
21       off limits to thr_kill(). If sig is 0, a validity check is done for the
22       existence of the target thread; no signal is sent.
23

RETURN VALUES

25       Upon successful completion, thr_kill() returns 0. Otherwise,  an  error
26       number is returned. In the event of failure, no signal is sent.
27

ERRORS

29       The thr_kill() function will fail if:
30
31       EINVAL    The  sig  argument  value is not zero and is an invalid or an
32                 unsupported signal number.
