   the application. 

   `conn' is the associated client connection. `cmd_payload' is the command
   payload data received from server and it can be ignored. It is provided
   if the application would like to re-parse the received command data,
   however, it must be noted that the data is parsed already by the library
   thus the payload can be ignored. `success' is FALSE if error occured.
   In this case arguments are not sent to the application. `command' is the

   and each command defines the number and type of arguments it passes to the
   application (on error they are not sent). */
