int sig);
DESCRIPTION
The
thr_kill() function sends the
sig signal to the thread designated

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

sig is
0, a validity check
is done for the existence of the target thread; no signal is sent.

0. Otherwise, an
error number is returned. In the event of failure, no signal is sent.
