## Description

On some protocols it's possible to determine the type of client another user is using, ranging from a simple "phone or not?" indicator to a classification into several types of user interface. Telepathy represents these using the client types defined by XMPP.

This section documents the auto-generated C wrappers for the ClientTypes interface, used with TpConnection objects.

### tp_cli_connection_interface_client_types_call_get_client_types ()

    TpProxyPendingCall * tp_cli_connection_interface_client_types_call_get_client_types
                                                            (TpConnection *proxy,
                                                             gint timeout_ms,

                                                             tp_cli_connection_interface_client_types_callback_for_get_client_types callback,
                                                             gpointer user_data,

                                                             GObject *weak_object);

Start a GetClientTypes method call.

Return the client types of the given contacts, if they are already known. If any of the given contacts' client types are not known, request their current client types, but return immediately without waiting for a reply; if a reply with a non-empty client type array is later received for those contacts, the <tp:member-ref>ClientTypesUpdated</tp:member-ref> signal will be emitted for them. <tp:rationale> This method is appropriate for &quot;lazy&quot; client type finding, for instance displaying the client types (if available) of everyone in your contact list. </tp:rationale>

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_Contacts` : | Used to pass an 'in' argument: The contacts whose client types should be returned or signalled.
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

### tp_cli_connection_interface_client_types_call_request_client_types ()

                                                             gint timeout_ms,

Start a RequestClientTypes method call.

Return the current client types of the given contact. If necessary, make a request to the server for up-to-date information, and wait for a reply. <tp:rationale> This method is appropriate for use in a &quot;Contact Information...&quot; dialog; it can be used to show progress information (while waiting for the method to return), and can distinguish between various error conditions. </tp:rationale>

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_Contact` : | Used to pass an 'in' argument: The contact whose client types should be returned. (TpContactHandle)
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

Signature of the callback called when a GetClientTypes method call succeeds or fails.

`proxy` : | the proxy on which the call was made
`out_Client_Types` : | Used to return an 'out' argument if `error` is `NULL`: The contacts' client types, if already known. Contacts whose client types are not already known are omitted from the mapping; contacts known to have no client type information appear in the mapping with an empty list.
`error` : | `NULL` on success, or an error on failure
`user_data` : | user-supplied data
`weak_object` : | user-supplied object

Signature of the callback called when a RequestClientTypes method call succeeds or fails.

`proxy` : | the proxy on which the call was made
`out_Client_Types` : | Used to return an 'out' argument if `error` is `NULL`: The contact's client types. It MAY be empty, indicating that no client type information was found.
`error` : | `NULL` on success, or an error on failure
`user_data` : | user-supplied data

Connect a handler to the signal ClientTypesUpdated.

Emitted when a contact's client types change or become known.

`proxy` : | A TpConnection or subclass
`callback` : | Callback to be called when the signal is received
`user_data` : | User-supplied data for the callback
`destroy` : | Destructor for the user-supplied data, which will be called when this signal is disconnected, or before this function returns `NULL`
`weak_object` : | A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected
`error` : | If not `NULL`, used to raise an error if `NULL` is returned
Returns : | a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or `NULL` if the proxy does not have the desired interface or has become invalid.
