  * Description:
  *   The client code must call this function periodically to process
- *   incoming messages from the server.
+ *   incoming messages from the server.  If CONFIG_NX_BLOCKING is defined,
+ *   then this function not return until a server message is received.
+ *
+ *   When CONFIG_NX_BLOCKING is not defined, the client must exercise
+ *   caution in the looping to assure that it does not eat up all of
+ *   the CPU bandwidth calling nx_eventhandler repeatedly.  nx_eventnotify
+ *   may be called to get a signal event whenever a new incoming server
+ *   event is avaiable.
  *
  * Input Parameters:
  *   handle - the handle returned by nx_connect
  *
  * Return:
- *   >0: The length of the message received in msgbuffer
- *    0: No message was received
- *   <0: An error occurred and errno has been set appropriately
- *
- *   Of particular interest, it will return errno == EHOSTDOWN when the
- *   server is disconnected.  After that event, the handle can not longer
- *   be used.
+ *     OK: No errors occurred.  If CONFIG_NX_BLOCKING is defined, then
+ *         one or more server message was processed.
+ *  ERROR: An error occurred and errno has been set appropriately.  Of
+ *         particular interest, it will return errno == EHOSTDOWN when the
+ *         server is disconnected.  After that event, the handle can no
+ *         longer be used.
