Action function for this command. Parameters: args  command-line arguments (less the command verb) msgtype  ISIS message-type code (see isismessage.h) reply  string with the command return reply (info or error message) Command action functions take the form int cmd_xxx(char *args, MsgType msgtype, char *reply){} They return one of three integer return status values (defined in commands.h): CMD_OK command execution completed OK, reply contains the command output string to return to the caller. CMD_NOOP command execution OK, but nothing to return to the caller (reply is empty, command requires no reply service). CMD_ERR command execution resulted in an error, reply contains the error message to return to the caller. See the individual command action functions implemented in commands.c for details.
