| Name | Description | Variable Arguments |
| SILC_COMMAND_WHOIS | Returns information about user. The following pointers may be NULL: 'channels', 'fingerprint', 'channel_usermodes' and 'attrs'. If 'fingerprint' is valid its length is 20 bytes. If 'channels' is valid each entry in the list is SilcChannelPayload. If the `channel_usermodes' is valid then the table has as many entries as there are entries in the `channels' list, and the first entry in the table is the user mode on the first channel in the `channels' list. The `channel_usermodes' is the table of the user's modes on the joined channels. The 'attr' is the Requested Attributes that may have been returned by the client and it can be parsed by traversing the SilcDList and using silc_attribute_get_attribute function. Each entry in the list is SilcAttribute. | SilcClientEntry client_entry, char *nickname, char *username, char *realname, SilcDList channels, SilcUInt32 usermode, SilcUInt32 idletime, unsigned char *fingerprint, SilcUInt32 *channel_usermodes, SilcDList attrs |
| SILC_COMMAND_WHOWAS | Returns history information about user. The 'client_entry' and 'realname' may be NULL. | SilcClientEntry client_entry, char *nickname, char *username, char *realname |
| SILC_COMMAND_IDENTIFY | Returns information about user, channel or server. This is similar to WHOIS command but does not return so much information and can be used to get information about channels and servers too. Application should ignore this command reply. The 'name' and 'info' may be NULL. | void *entry, char *name, char *info |
| SILC_COMMAND_NICK | Returns the new Client ID and new nickname inside the SilcClientEntry. The `old_client_id' is the old Client ID used by the client before the nickname was changed. The `nickname' is the new nickname. Note that, when user changes nickname SILC_NOTIFY_TYPE_NICK_CHANGE is not delivered to application. Instead this SILC_COMMAND_NICK command reply is delivered. | SilcClientEntry local_entry, char *nickname, const SilcClientID *old_client_id |
| SILC_COMMAND_LIST | Returns the list of channel in the SILC network. Each call of command reply returns one channel. This means that the command reply is called multiple times to return list of channels. The 'channel', 'channel_name' and 'channel_topic' may be NULL. However, the 'channel' and 'channel_name' are NULL only if there are no channels in the network. In this case this reply is called once with all arguments set to NULL. Application must be able to handle this situation correctly. | SilcChannelEntry channel, char *channel_name, char *channel_topic, SilcUInt32 user_count |
| SILC_COMMAND_TOPIC | Returns the topic of the channel. | SilcChannelEntry channel, char *topic |
| SILC_COMMAND_INVITE | Returns the invite list of the channel. Called also even if invite list was not modified but SILC_COMMAND_INVITE command was used to invite a user into a channel. In this case the invite list is not returned by the server and 'invite_list' is NULL. The 'invite_list' is SilcArgumenPayload which contains one or more arguments, each is one invite list entry. The entries can be retrieved with silc_argument_get_first_arg, silc_argument_get_next_arg, silc_argument_get_arg_type and silc_argument_get_decoded functions. | SilcChannelEntry channel, SilcArgumentPayload invite_list |
| SILC_COMMAND_KILL | Called after killing a client. Returns the client that was killed. The `client_entry' may be NULL. The `client_entry' will become invalid after the command reply has returned from application. The SILC_NOTIFY_TYPE_KILLED will not be delivered for clients that you killed. | SilcClientEntry client_entry |
| SILC_COMMAND_INFO | Returns information about the server user is connected to. | SilcServerEntry server, char *server_name, char *server_info |
| SILC_COMMAND_STATS | Returns network statistics from the server. The `stats' structure contains the statistics returned by the server. | SilcClientStats *stats |
| SILC_COMMAND_PING | Returns reply to earlier ping. There is no arguments to this reply. | none |
| SILC_COMMAND_OPER | Returns reply to earlier SILC_COMMAND_OPER command. There is no arguments to this reply. | none |
| SILC_COMMAND_JOIN | Reply received when user joined a channel. The `channel_mode' contains the current channel mode. The `user_list' is the user list on the channel and may be traversed with silc_hash_table_get function. Each entry in the `user_list' is SilcChannelUser structure, which contains the SilcClientEntry and the client's mode on the channel. The library will free the list. The `topic' is the current topic on channel or NULL if no topic is set. The `cipher' is the encryption algorithm used on channel or NULL if it is not available. The `hmac' is the HMAC algorithm used on channel or NULL if it is not available. The `founder_key' is the channel founder's public key or NULL if founder public key has not been set. The `channel_pubkeys' is a list of channel public keys (for authentication on joining) or NULL if they have not been set. Each entry in the list is SilcArgumentDecodedList each containing one channel SilcPublicKey. The library will free the list. | char *channel_name, SilcChannelEntry channel, SilcUInt32 channel_mode, SilcHashTableList *user_list, char *topic, char *cipher, char *hmac, SilcPublicKey founder_key, SilcDList channel_pubkeys, SilcUint32 user_limit |
| SILC_COMMAND_MOTD | Returns the Message of the Day from the server. The 'motd' may be NULL. | char *motd |
| SILC_COMMAND_UMODE | Returns the user mode after changing it. | SilcUInt32 user_mode |
| SILC_COMMAND_CMODE | Returns channel's mode after changing it. Optionally may also return founder's public key when it was set. It may also return the channel public key list when the list was altered. The 'founder_key' and 'channel_pubkeys' arguments may be NULL. The 'channel_pubkeys' is a list of SilcArgumentDecodedList contexts which each contain one channel public key. The library will automatically free the list. If the `founder_key' was present it will be updated to `channel' entry by the library after calling the command_reply callback. Application may check if the `founder_key' is different from the key in `channel' entry to detect if it was changed. | SilcChannelEntry channel, SilcUInt32 mode, SilcPublicKey founder_key, SilcDList channel_pubkeys, SilcUint32 user_limit |
| SILC_COMMAND_CUMODE | Returns user's mode on channel after changing it. | SilcUInt32 mode, SilcChannelEntry channel, SilcClientEntry target_client |
| SILC_COMMAND_KICK | Called after kicking a client. Returns the client that was kicked from the 'channel'. | SilcChannelEntry channel, SilcClientEntry client_entry |
| SILC_COMMAND_BAN | Returns channel's ban list. The 'ban_list' may be NULL. The construction of that list is equivalent to invite list. See description of SILC_COMMAND_INVITE command reply. | SilcChannelEntry channel, SilcArgumentPayload ban_list |
| SILC_COMMAND_DETACH | Called after being detached from the SILC network. The command reply delivers the detachment data buffer `detach_data' that the application should save for example into a file. The data will be needed when resuming back to the network. When resuming the data is saved into SilcClientConnectionParams structure and given as argument to silc_client_connect_to_server or silc_client_key_exchange functions. | SilcBuffer detach_data |
| SILC_COMMAND_WATCH | Called after modifying the watch list in the server. There is no arguments to this reply. | none |
| SILC_COMMAND_SILCOPER | Returns reply to earlier SILC_COMMAND_SILCOPER command. There is no arguments to this reply. | none |
| SILC_COMMAND_LEAVE | Called after leaving the channel. Note that the `channel' will become invalid after command_reply client operation returns. | SilcChannelEntry channel |
| SILC_COMMAND_USERS | Returns list of users in channel. The `user_list' may be traversed with silc_hash_table_get function. Each entry in the `user_list' is SilcChannelUser structure, which contains the SilcClientEntry and the client's mode on the channel. | SilcChannelEntry channel, SilcHashTableList *user_list |
| SILC_COMMAND_GETKEY | Returns public key of client or server. The 'public_key' may be NULL. The 'entry_type' is used to check what type of pointer the entry' is. For SILC_ID_CLIENT SilcClientEntry and for SILC_ID_SERVER SilcServerEntry. | SilcIdType entry_type, void *entry, SilcPublicKey public_key |
| SILC_COMMAND_SERVICE | Returns the service list in the server, or information on the accepted and authenticated service. The 'service_list' maybe NULL if server does not support any services. It is NULL also when 'name' is not NULL. The 'service_list' is a comma separated list of services the server supports. The 'name' MAY be NULL also. The 'name' is the requested service, and it is non-NULL only if server accepted and authenticated client's request. | const char *server_list, const char *service_name |
