## Description

The old asynchronous API was deprecated since 3.0 and is replaced with their an equivalent version which has a detailed GError structure in the asynchronous callback, instead of a status code only.

As an example, `e_book_async_open()` is replaced by `e_book_open_async()`.

## Details

### struct EBook

    struct EBook;

### Warning

`EBook` is deprecated and should not be used in newly-written code.

### e_book_new ()

    EBook *             e_book_new                          (ESource *source,
                                                             GError **error);

### Warning

`e_book_new` has been deprecated since version 3.2 and should not be used in newly-written code. Use `e_book_client_new()` instead.

Creates a new EBook corresponding to the given `source`. There are only two operations that are valid on this book at this point: `e_book_open()`, and `e_book_remove()`.

`source` : | an ESource
`error` : | return location for a GError, or `NULL`
Returns : | a new but unopened EBook.

### e_book_remove ()

    gboolean            e_book_remove                       (EBook *book,
                                                             GError **error);

### Warning

`e_book_remove` has been deprecated since version 3.2 and should not be used in newly-written code. Use `e_client_remove_sync()` on an EBookClient object instead.

Removes the backing data for this EBook. For example, with the file backend this deletes the database file. You cannot get it back!

`book` : | an EBook
`error` : | a GError to set on failure
Returns : | `TRUE` on success, `FALSE` on failure.

### e_book_open ()

    gboolean            e_book_open                         (EBook *book,
                                                             gboolean only_if_exists,

### Warning

`e_book_open` has been deprecated since version 3.2 and should not be used in newly-written code. Use `e_client_open_sync()` on an EBookClient object instead.

Opens the addressbook, making it ready for queries and other operations.

`book` : | an EBook
`only_if_exists` : | if `TRUE`, fail if this book doesn't already exist, otherwise create it first
`error` : | a GError to set on failure
Returns : | `TRUE` if the book was successfully opened, `FALSE` otherwise.

### e_book_get_supported_fields ()

    gboolean            e_book_get_supported_fields         (EBook *book,

### Warning

`e_book_get_supported_fields` has been deprecated since version 3.2 and should not be used in newly-written code. Use `e_client_get_backend_property_sync()` on an EBookClient object with BOOK_BACKEND_PROPERTY_SUPPORTED_FIELDS instead.

Gets a list of fields that can be stored for contacts in this `book`. Other fields may be discarded. The list will contain pointers to allocated strings, and both the GList and the strings must be freed by the caller.

`book` : | an EBook
`fields` : | a GList of fields to set on success. [out][transfer full][element-type utf8]
`error` : | a GError to set on failure
Returns : | `TRUE` if successful, `FALSE` otherwise

### e_book_get_supported_auth_methods ()

    gboolean            e_book_get_supported_auth_methods   (EBook *book,

### Warning

`e_book_get_supported_auth_methods` has been deprecated since version 3.2 and should not be used in newly-written code. Use `e_client_get_backend_property_sync()` on an EBookClient object with BOOK_BACKEND_PROPERTY_SUPPORTED_AUTH_METHODS instead.

Queries `book` for the list of authentication methods it supports. The list will contain pointers to allocated strings, and both the GList and the strings must be freed by the caller.

`book` : | an EBook
`auth_methods` : | a GList of auth methods to set on success. [out][transfer full][element-type utf8]
`error` : | a GError to set on failure
