### Constructor

# Gio DBusServer new_sync

since: 2.26

#### Declaration

    GDBusServer*
    g_dbus_server_new_sync (
      const gchar* address,
      GDBusServerFlags flags,
      const gchar* guid,
      GDBusAuthObserver* observer,
      GCancellable* cancellable,
      GError** error
    )

#### Description

Creates a new D-Bus server that listens on the first address in `address` that works.

Once constructed, you can use `g_dbus_server_get_client_address()` to get a D-Bus address string that clients can use to connect.

To have control over the available authentication mechanisms and the users that are authorized to connect, it is strongly recommended to provide a non-`NULL` `GDBusAuthObserver`.

Connect to the `GDBusServer::new-connection` signal to handle incoming connections.

The returned `GDBusServer` isn’t active - you have to start it with g_dbus_server_start().

`GDBusServer` is used in this [example][gdbus-peer-to-peer].

This is a synchronous failable constructor. There is currently no asynchronous version.

Available since: 2.26

#### Parameters

`address`

  Type: `const gchar*`

  A D-Bus address.

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

`flags`

  Type: `GDBusServerFlags`

  Flags from the `GDBusServerFlags` enumeration.

`guid`

  Type: `const gchar*`

  A D-Bus GUID.

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

`observer`

  Type: `GDBusAuthObserver`

  A `GDBusAuthObserver` or `NULL`.

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

`cancellable`

  Type: `GCancellable`

  A `GCancellable` or `NULL`.

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

`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 constructor 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: `GDBusServer`

A `GDBusServer` or `NULL` if `error` is set. Free with g_object_unref().

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