pthread_kill(pthread_t thread, int sig);

The pthread_kill() function sends a signal, specified by sig, to a thread, specified by thread. If sig is 0, error checking is performed, but no signal is actually sent.

If successful, pthread_kill() returns 0. Otherwise, an error number is returned.

pthread_kill() will fail if:
thread is an invalid thread ID.
sig is an invalid or unsupported signal number.
