### Method

# EBook BookClientget_contacts_sync

since: 3.2

#### Declaration [src]

    gboolean
    e_book_client_get_contacts_sync (
      EBookClient* client,
      const gchar* sexp,
      GSList** out_contacts,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Query `client` with `sexp`, receiving a list of contacts which matched. If successful, then the `out_contacts` is set to newly allocated `GSList` of `EContact`(s), which should be freed with e_client_util_free_object_slist().

Note: `sexp` can be obtained through `EBookQuery`, by converting it to a string with e_book_query_to_string().

Available since: 3.2
