+      * DOCPUBLIC
+      *      This function specifies the size of the stack on
+      *      which threads created with 'attr' will run.
+      *
+      * PARAMETERS
+      *      attr
+      *              pointer to an instance of pthread_attr_t
+      *
+      *      stacksize
+      *              stack size, in bytes.
+      *
+      *
+      * DESCRIPTION
+      *      This function specifies the size of the stack on
+      *      which threads created with 'attr' will run.
+      *
+      *      NOTES:
+      *              1)      Function supported only if this macro is
+      *                      defined:
+      *
+      *                              _POSIX_THREAD_ATTR_STACKSIZE
+      *
+      *              2)      Find the default first (using
+      *                      pthread_attr_getstacksize), then increase
+      *                      by multiplying.
+      *
+      *              3)      Only use if thread needs more than the
+      *                      default.
+      *
+      * RESULTS
+      *              0               successfully set stack size,
+      *              EINVAL          'attr' is invalid or stacksize too
+      *                              small or too big.
+      *              ENOSYS          function not supported
+      *
