Gio.DtlsConnection.close

### Method

# Gio DtlsConnectionclose

since: 2.48

#### Declaration

    gboolean
    g_dtls_connection_close (
      GDtlsConnection* conn,
      GCancellable* cancellable,
      GError** error
    )

#### Description

Close the DTLS connection. This is equivalent to calling `g_dtls_connection_shutdown()` to shut down both sides of the connection.

Closing a `GDtlsConnection` waits for all buffered but untransmitted data to be sent before it completes. It then sends a `close_notify` DTLS alert to the peer and may wait for a `close_notify` to be received from the peer. It does not close the underlying `GDtlsConnection:base-socket`; that must be closed separately.

Once `conn` is closed, all other operations will return `G_IO_ERROR_CLOSED`. Closing a `GDtlsConnection` multiple times will not return an error.

`GDtlsConnections` will be automatically closed when the last reference is dropped, but you might want to call this function to make sure resources are released as early as possible.

If `cancellable` is cancelled, the `GDtlsConnection` may be left partially-closed and any pending untransmitted data may be lost. Call `g_dtls_connection_close()` again to complete closing the `GDtlsConnection`.

Available since: 2.48

#### Parameters

`cancellable`

  Type: `GCancellable`

  A `GCancellable`, 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: `gboolean`

`TRUE` on success, `FALSE` otherwise.
