- * Name: nx_eventhandler
- *
- * Description:
- * The client code must call this function periodically to process
- * 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:
- * 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.
