    - * PurpleProtocolChatInterface:
    - * @info: Returns a list of #PurpleProtocolChatEntry structs, which represent
    - * information required by the protocol to join a chat. libpurple will
    - * call join_chat along with the information filled by the user.
    - * <sbr/>Returns: A list of #PurpleProtocolChatEntry's
    - * @info_defaults: Returns a hashtable which maps #PurpleProtocolChatEntry
    - * struct identifiers to default options as strings based on
    - * @chat_name. The resulting hashtable should be created with
    - * #g_hash_table_new_full(#g_str_hash, #g_str_equal, %NULL,

    - * name from a hashtable.
    - * <sbr/>@chat_name: The chat name to be turned into components
    - * <sbr/>Returns: Hashtable containing the information extracted
    - * from @chat_name
    - * @join: Called when the user requests joining a chat. Should arrange for
    - * purple_serv_got_joined_chat() to be called.
    - * <sbr/>@components: A hashtable containing information required to join
    - * the chat as described by the entries returned by
    - * @info. It may also be called when accepting an
    - * invitation, in which case this matches the data
    - * parameter passed to purple_serv_got_chat_invite().
    - * @reject: Called when the user refuses a chat invitation.
    - * <sbr/>@components: A hashtable containing information required to
    - * join the chat as passed to purple_serv_got_chat_invite().
    - * @get_name: Returns a chat name based on the information in components. Use
    - * @info_defaults if you instead need to generate a hashtable from a
    - * chat name.
    - * <sbr/>@components: A hashtable containing information about the
    - * chat.
    - * @invite: Invite a user to join a chat.
    - * <sbr/>@id: The id of the chat to invite the user to.
    - * <sbr/>@message: A message displayed to the user when the invitation
    - * is received.
    - * <sbr/>@who: The name of the user to send the invation to.
    - * @leave: Called when the user requests leaving a chat.
    - * <sbr/>@id: The id of the chat to leave
    - * @send: Send a message to a chat.
    - * <sbr/>This protocol function should return a positive value on
    - * success. If the message is too big to be sent, return
    - * <literal>-E2BIG</literal>. If the account is not connected,
    - * return <literal>-ENOTCONN</literal>. If the protocol is unable
    - * to send the message for another reason, return some other
    - * negative value. You can use one of the valid #errno values, or
    - * just big something.
    - * <sbr/>@id: The id of the chat to send the message to.
    - * <sbr/>@msg: The message to send to the chat.
    - * <sbr/>Returns: A positive number or 0 in case of success, a
    - * negative error number in case of failure.
    - * @get_user_real_name: Gets the real name of a participant in a chat. For
    - * example, on XMPP this turns a chat room nick
    - * <literal>foo</literal> into
    - * <literal>room\@server/foo</literal>.
    - * <sbr/>@gc: the connection on which the room is.
    - * <sbr/>@id: the ID of the chat room.
    - * <sbr/>@who: the nickname of the chat participant.

    - * string must be freed by the caller.
    - *

    +/**
    + * PurpleProtocolChatInterface:
    + * @info: Returns a list of #PurpleProtocolChatEntry structs, which represent
    + * information required by the protocol to join a chat. libpurple will
    + * call join_chat along with the information filled by the user.
    + * @info_defaults: Returns a hashtable which maps #PurpleProtocolChatEntry
    + * struct identifiers to default options as strings based on
    + * @chat_name. The resulting hashtable should be created with
    + * #g_hash_table_new_full(#g_str_hash, #g_str_equal, %NULL,
    + * #g_free). Use @get_name if you instead need to extract a chat
    + * name from a hashtable.
    + * @join: Called when the user requests joining a chat. Should arrange for
    + * purple_serv_got_joined_chat() to be called.
    + * @reject: Called when the user refuses a chat invitation.
    + * @get_name: Returns a chat name based on the information in components. Use
    + * @info_defaults if you instead need to generate a hashtable from a
    + * chat name.
    + * @invite: Invite a user to join a chat.
    + * @leave: Called when the user requests leaving a chat.
    + * @send: Send a message to a chat.
    + * @get_user_real_name: Gets the real name of a participant in a chat. For
    + * example, on XMPP this turns a chat room nick
    + * <literal>foo</literal> into
    + * <literal>room\@server/foo</literal>.
    + * @set_topic: Called to set the topic for the given chat.
    + *
    + * The protocol chat interface.
    + *
    + * This interface provides callbacks needed by protocols that implement chats.
