Virtual Method


since: 2.48


shutdown (
  GDtlsConnection* conn,
  gboolean shutdown_read,
  gboolean shutdown_write,
  GCancellable* cancellable,
  GError** error


Shut down part or all of a DTLS connection.

If shutdown_read is TRUE then the receiving side of the connection is shut down, and further reading is disallowed. Subsequent calls to g_datagram_based_receive_messages() will return G_IO_ERROR_CLOSED.

If shutdown_write is TRUE then the sending side of the connection is shut down, and further writing is disallowed. Subsequent calls to g_datagram_based_send_messages() will return G_IO_ERROR_CLOSED.

It is allowed for both shutdown_read and shutdown_write to be TRUE — this is equivalent to calling g_dtls_connection_close().

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

A GCancellable, or NULL.

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

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 left initialized to NULL by the virtual function 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.
