50 * This function requests that a signal be delivered to the
51 * specified thread. If sig is zero, error checking is
52 * performed but no signal is actually sent such that this
53 * function can be used to check for a valid thread ID.
54 *
55 * PARAMETERS
56 * thread reference to an instances of pthread_t
57 * sig signal. Currently only a value of 0 is supported.

61 * This function requests that a signal be delivered to the
62 * specified thread. If sig is zero, error checking is
63 * performed but no signal is actually sent such that this
64 * function can be used to check for a valid thread ID.
65 *
66 * RESULTS
67 * ESRCH the thread is not a valid thread ID,
68 * EINVAL the value of the signal is invalid
69 * or unsupported.
70 * 0 the signal was successfully sent.
