## Description

## Functions

### camel_service_migrate_files ()

    void
    camel_service_migrate_files (CamelService *service);

Since: 3.4

### camel_service_new_camel_url ()

    CamelURL *
    camel_service_new_camel_url (CamelService *service);

Returns a new CamelURL representing `service` . Free the returned CamelURL with `camel_url_free()`.

### camel_service_get_display_name ()

    const gchar *
    camel_service_get_display_name (CamelService *service);

Returns the display name for `service` , or `NULL` if `service` has not been given a display name. The display name is intended for use in a user interface and should generally be given a user-defined name.

Compare this with `camel_service_get_name()`, which returns a built-in description of the type of service (IMAP, SMTP, etc.).

service | a CamelService |

#### Returns

the display name for `service` , or `NULL`

Since: 3.2

### camel_service_dup_display_name ()

    gchar *
    camel_service_dup_display_name (CamelService *service);

Thread-safe variation of `camel_service_get_display_name()`. Use this function when accessing `service` from multiple threads.

The returned string should be freed with `g_free()` when no longer needed.

Adds `task` to a queue of waiting tasks with the same source object. Queued tasks execute one at a time in the order they were added. When `task` reaches the front of the queue, it will be dispatched by invoking `task_func` in a separate thread. If `task` is cancelled while queued, it will complete immediately with an appropriate error.

This is primarily intended for use by CamelStore, CamelTransport and CamelFolder to achieve ordered invocation of synchronous class methods.
