# EDataBook BookBackendget_contact_sync

since: 3.10

#### Declaration [src]

    EContact*
    e_book_backend_get_contact_sync (
      EBookBackend* backend,
      const gchar* uid,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Obtains an `EContact` for `uid`.

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

If an error occurs, the function will set `error` and return `NULL`.

Available since: 3.10

#### Parameters

`uid`

  Type: `const gchar*`

  A contact ID.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`cancellable`

  Type: `GCancellable`

  Optional `GCancellable` object, or `NULL`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `EContact`

An `EContact`, or `NULL` on error.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
