`service` : | a CamelService
Returns : | the base cache directory for `service`

Since 3.4

### camel_service_get_name ()

    gchar *             camel_service_get_name              (CamelService *service,
                                                             gboolean brief);

This gets the name of the service in a "friendly" (suitable for humans) form. If `brief` is `TRUE`, this should be a brief description such as for use in the folder tree. If `brief` is `FALSE`, it should be a more complete and mostly unambiguous description.

`service` : | a CamelService
`brief` : | whether or not to use a briefer form
Returns : | a description of the service which the caller must free

### camel_service_get_provider ()

    CamelProvider *     camel_service_get_provider          (CamelService *service);

Gets the CamelProvider associated with the service.

`service` : | a CamelService
Returns : | the CamelProvider

### camel_service_ref_session ()

    struct _CamelSession * camel_service_ref_session        (CamelService *service);

Returns the CamelSession associated with the service.

The returned CamelSession is referenced for thread-safety. Unreference the CamelSession with `g_object_unref()` when finished with it.

`service` : | a CamelService
Returns : | the CamelSession

Since 3.8

### camel_service_ref_settings ()

    CamelSettings *     camel_service_ref_settings          (CamelService *service);

Returns the CamelSettings instance associated with the service.

The returned CamelSettings is referenced for thread-safety and must be unreferenced with `g_object_unref()` when finished with it.

`service` : | a CamelService
Returns : | the CamelSettings

Since 3.6

### camel_service_set_settings ()

    void                camel_service_set_settings          (CamelService *service,
                                                             CamelSettings *settings);

Associates a new CamelSettings instance with the service. The `settings` instance must match the settings type defined in CamelServiceClass. If `settings` is `NULL`, a new CamelSettings instance of the appropriate type is created with all properties set to defaults.

`service` : | a CamelService
`settings` : | an instance derviced from CamelSettings, or `NULL`

Since 3.2

### camel_service_get_uid ()

    const gchar *       camel_service_get_uid               (CamelService *service);

Connects `service` to a remote server using the information in its "settings" instance.

If a connect operation is already in progress when this function is called, its results will be reflected in this connect operation.

`service` : | a CamelService
`cancellable` : | optional GCancellable object, or `NULL`
`error` : | return location for a GError, or `NULL`
Returns : | `TRUE` if the connection is made or `FALSE` otherwise

Since 3.6

### camel_service_connect ()

    void                camel_service_connect               (CamelService *service,

Asynchronously connects `service` to a remote server using the information in its "settings" instance.

If a connect operation is already in progress when this function is called, its results will be reflected in this connect operation.

If any disconnect operations are in progress when this function is called, they will be cancelled.

When the operation is finished, `callback` will be called. You can then call `camel_service_connect_finish()` to get the result of the operation.

`service` : | a CamelService
`io_priority` : | the I/O priority of the request
`cancellable` : | optional GCancellable object, or `NULL`
`callback` : | a GAsyncReadyCallback to call when the request is satisfied

Disconnect from the service. If `clean` is `FALSE`, it should not try to do any synchronizing or other cleanup of the connection.

If a disconnect operation is already in progress when this function is called, its results will be reflected in this disconnect operation.

If any connect operations are in progress when this function is called, they will be cancelled.

`service` : | a CamelService
`clean` : | whether or not to try to disconnect cleanly
`cancellable` : | optional GCancellable object, or `NULL`
`error` : | return location for a GError, or `NULL`
Returns : | `TRUE` if the connection was severed or `FALSE` otherwise

If a disconnect operation is already in progress when this function is called, its results will be reflected in this disconnect operation.

If any connect operations are in progress when this function is called, they will be cancelled.

When the operation is finished, `callback` will be called. You can then call `camel_service_disconnect_finish()` to get the result of the operation.

`service` : | a CamelService
`clean` : | whether or not to try to disconnect cleanly
`io_priority` : | the I/O priority of the request
`cancellable` : | optional GCancellable object, or `NULL`

    typedef enum {
    	CAMEL_AUTHENTICATION_ERROR,
    	CAMEL_AUTHENTICATION_ACCEPTED,

Attempts to authenticate `service` using `mechanism` and, if necessary, `service`'s "password" property. The function makes only ONE attempt at authentication and does not loop.

If the authentication attempt completed and the server accepted the credentials, the function returns CAMEL_AUTHENTICATION_ACCEPTED.

If the authentication attempt completed but the server rejected the credentials, the function returns CAMEL_AUTHENTICATION_REJECTED.

If the authentication attempt failed to complete due to a network communication issue or some other mishap, the function sets `error` and returns CAMEL_AUTHENTICATION_ERROR.

Generally this function should only be called from a CamelSession subclass in order to implement its own authentication loop.
