#### Returns

`TRUE` if the contact was found and removed, `FALSE` otherwise.

### e_book_backend_db_cache_check_contact ()

    gboolean
    e_book_backend_db_cache_check_contact (struct __db *db,
                                           const gchar *uid);

`e_book_backend_db_cache_check_contact` has been deprecated since version 3.12 and should not be used in newly-written code.
