+/****h* silcclient/Client Library Interface
+ *
+ * DESCRIPTION
+ *
+ * This header file includes the SilcClientEntry, SilcChannelEntry and
+ * SilcServer entry structures and various routines to search, resolve and
+ * handle these structures.
+ *
+ * All entries (SilcClientEntry, SilcChannelEntry and SilcServerEntry) are
+ * reference counted. If application wishes to save an entry pointer it must
+ * always first acquire a reference. The reference must be released once the
+ * entry is not needed anymore. If application wants to read any data from
+ * the entry structure it must first lock the entry. This protects access to
+ * the entries in multithreaded environment. If threads are not used, locking
+ * the entries is not needed. They however still must be referenced even
+ * when threads are not used.

* it should always duplicated them.
*
* None of the string arrays are set if the first character is '\0'.
- * All string arrays are always NULL terminated.
+ * All string arrays are always zero ('\0') terminated.
*
* If application stores the SilcClientEntry it must always take
* a reference of it by calling silc_client_ref_client function. The

+ * DESCRIPTION
+ *
+ * Acquires lock for the client entry indicate by `client_entry'. When

+ * NOTES
+ *
+ * The entry must be unlocked before calling any Client Library API
+ * functions where the entry is given as argument, unless otherwise stated.
+ *
+ * The entry should not be locked for long periods of time. For example,
+ * it is not appropriate to hold the lock while waiting user interface to
+ * be drawn. The appropriate way is to read the data and duplicate it if
+ * necessary, unlock the entry, then draw on the user interface.
+ *
+ * This function is not needed if application is not multithreaded.

- * SilcGetClientCallback completion,
- * void *context);

- * DESCRIPTION
- *
- * Gets client entries by the channel indicated by `channel'. Thus,
- * it resovles the users currently on that channel. If all users are
- * already resolved this returns the users from the channel. If the
- * users are resolved only partially this resolves the complete user
- * information. If no users are resolved on this channel at all, this
- * calls USERS command to resolve all users on the channel. The `completion'
- * will be called after the entries are available. When server returns
- * the client information it will be cached and can be accessed locally
- * at a later time.
- *
- * This function can be used for example in SILC_COMMAND_JOIN command
- * reply handling in application to resolve users on that channel. It
- * also can be used after calling silc_client_get_channel_resolve to
- * resolve users on that channel.
- *
- * NOTES
- *
- * The resolving is done with WHOIS command. For this reason this
- * command may take a long time because it resolves detailed user
- * information.
