     int
     pthread_kill(pthread_t thread, int sig);

DESCRIPTION

     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.

RETURN VALUES

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

ERRORS

     pthread_kill() will fail if:

     [ESRCH]            thread is an invalid thread ID.

     [EINVAL]           sig is an invalid or unsupported signal number.
