pthread_kill(pthread_t thread, int sig);
DESCRIPTION
The pthread_kill() function sends a signal, specified by sig, to a
thread, specified by thread. The signal will be handled in the context
of thread, but the signal action may alter the process as a whole. If
sig is 0, error checking is performed, but no signal is actually sent.
RETURN VALUES
If successful, pthread_kill() returns 0. Otherwise, an error number is
returned.
ERRORSpthread_kill() shall fail if:
[EINVAL] sig is an invalid or unsupported signal number.
[ESRCH] thread is an invalid thread ID.
