Returns the base directory under which to store user-specific mail data.

session :

a CamelSession

Returns :

the base directory for mail data

Since 3.2


camel_session_get_user_cache_dir ()

const gchar *       camel_session_get_user_cache_dir    (CamelSession *session);

camel_session_add_service ()

                                                         const gchar *protocol,
                                                         CamelProviderType type,
                                                         GError **error);

Instantiates a new CamelService for session. The uid identifies the service for future lookup. The protocol indicates which CamelProvider holds the GType of the CamelService subclass to instantiate. The type explicitly designates the service as a CamelStore or CamelTransport.

If the given uid has already been added, the existing CamelService with that uid is returned regardless of whether it agrees with the given protocol and type.

If no CamelProvider is available to handle the given protocol, or if the CamelProvider does not specify a valid GType for type, the function sets error and returns NULL.

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

session :

a CamelSession

uid :

a unique identifier string

protocol :

the service protocol

type :

the service type

error :

return location for a GError, or NULL

Returns :

a CamelService instance, or NULL. [transfer full]

camel_session_remove_service ()

void                camel_session_remove_service        (CamelSession *session,
                                                         CamelService *service);

Removes a CamelService previously added by camel_session_add_service().

session :

a CamelSession

service :

the CamelService to remove

Since 3.2


camel_session_ref_service ()

CamelService *      camel_session_ref_service           (CamelSession *session,
                                                         const gchar *uid);

Looks up a CamelService by its unique identifier string. The service must have been previously added using camel_session_add_service().

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

session :

a CamelSession

uid :

a unique identifier string

Returns :

a CamelService instance, or NULL. [transfer full]

Since 3.6


camel_session_ref_service_by_url ()

CamelService *      camel_session_ref_service_by_url    (CamelSession *session,
                                                         CamelURL *url,
                                                         CamelProviderType type);

Looks up a CamelService by trying to match its CamelURL against the given url and then checking that the object is of the desired type. The service must have been previously added using camel_session_add_service().

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

Note this function is significantly slower than camel_session_ref_service().

session :

a CamelSession

url :

a CamelURL

type :

a CamelProviderType

Returns :

a CamelService instance, or NULL. [transfer full]

Since 3.6


camel_session_list_services ()

GList *             camel_session_list_services         (CamelSession *session);

Returns a list of all CamelService objects previously added using camel_session_add_service().

The services returned in the list are referenced for thread-safety. They must each be unreferenced with g_object_unref() when finished with them. Free the returned list itself with g_list_free().

An easy way to free the list property in one step is as follows:

1
g_list_free_full (list, g_object_unref);

session :

a CamelSession

Returns :

an unsorted list of CamelService objects. [element-type CamelService][transfer full]

Since 3.2


camel_session_remove_services ()

void                camel_session_remove_services       (CamelSession *session);

Removes all CamelService instances added by camel_session_add_service().

This can be useful during application shutdown to ensure all CamelService instances are freed properly, especially since CamelSession instances are prone to reference cycles.

a CamelSession

Since 3.2


camel_session_get_password ()

gchar *             camel_session_get_password          (CamelSession *session,
                                                         CamelService *service,
                                                         const gchar *prompt,
                                                         const gchar *item,
                                                         guint32 flags,
                                                         GError **error);

This function is used by a CamelService to ask the application and the user for a password or other authentication data.

service and item together uniquely identify the piece of data the caller is concerned with.

prompt is a question to ask the user (if the application doesn't already have the answer cached). If CAMEL_SESSION_PASSWORD_SECRET is set, the user's input will not be echoed back.

If CAMEL_SESSION_PASSWORD_STATIC is set, it means the password returned will be stored statically by the caller automatically, for the current session.

The authenticator should set error to G_IO_ERROR_CANCELLED if the user did not provide the information. The caller must g_free() the information returned when it is done with it.

This function is used by a CamelService to tell the application that the authentication information it provided via camel_session_get_password() was rejected by the service. If the application was caching this information, it should stop, and if the service asks for it again, it should ask the user.

service and item identify the rejected authentication information, as with camel_session_get_password().

CamelJunkFilter *   camel_session_get_junk_filter       (CamelSession *session);

Returns the CamelJunkFilter instance used to classify messages as junk or not junk during filtering.

Note that CamelJunkFilter itself is just an interface. The application must implement the interface and install a CamelJunkFilter instance for junk filtering to take place.

                                                         GDestroyNotify notify);

Adds a function to be called whenever there are no higher priority events pending. If function returns FALSE it is automatically removed from the list of event sources and will not be called again.

This internally creates a main loop source using g_idle_source_new() and attaches it to session's own "main-context" using g_source_attach().

The priority is typically in the range between G_PRIORITY_DEFAULT_IDLE and G_PRIORITY_HIGH_IDLE.

session :

a CamelSession

priority :

the priority of the idle source

function :

data :

CamelSessionCallback ()

void                (*CamelSessionCallback)             (CamelSession *session,

                                                         GError **error);

This is the callback signature for jobs submitted to the CamelSession via camel_session_submit_job(). The error pointer is always non-NULL, so it's safe to dereference to check if a GError has been set.

session :

a CamelSession

cancellable :

                                                         GDestroyNotify notify);

This function provides a simple mechanism for providers to initiate low-priority background jobs. Jobs can be submitted from any thread, but execution of the jobs is always as follows:

1) The "job-started" signal is emitted from the thread in which session was created. This is typically the same thread that hosts the global default GMainContext, or "main" thread.

2) The callback function is invoked from a different thread where it's safe to call synchronous functions.

3) Once callback has returned, the "job-finished" signal is emitted from the same thread as "job-started" was emitted.

4) Finally if a notify function was provided, it is invoked and passed user_data so that user_data can be freed.

session :

a CamelSession

description :

human readable description of the job, shown to a user

callback :

                                                         GError **error);

Authenticates service, which may involve repeated calls to camel_service_authenticate() or camel_service_authenticate_sync(). A CamelSession subclass is largely responsible for implementing this, and should handle things like user prompts and secure password storage. These issues are out-of-scope for Camel.

If an error occurs, or if authentication is aborted, the function sets error and returns FALSE.
