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

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