+      * DOCPUBLIC
+      *      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.
+      *

+      * DESCRIPTION
+      *      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.
