- * Command reply functions are "the otherside" of the command functions.
- * Reply to a command sent by server is handled by these functions.
- *
- * The arguments received from server are also passed to the calling
- * application through command_reply client operation. The arguments are
- * exactly same and in same order as the server sent it. However, ID's are
- * not sent to the application. Instead, corresponding ID entry is sent
- * to the application. For example, instead of sending Client ID the
- * corresponding SilcClientEntry is sent to the application. The case is
- * same with for example Channel ID's. This way application has all the
- * necessary data already in hand without redundant searching. If ID is
- * received but ID entry does not exist, NULL is sent.
