Functions

GstNetControlMessageMeta *	gst_buffer_add_net_control_message_meta ()
#define	gst_buffer_get_net_control_message_meta()
const GstMetaInfo *	gst_net_control_message_meta_get_info ()

GstNetControlMessageMeta

Includes

#include <gst/net/gstnetcontrolmessagemeta.h>

Description

GstNetControlMessageMeta can be used to store control messages (ancillary data) which was received with or is to be sent alongside the buffer data. When used with socket sinks and sources which understand this meta it allows sending and receiving ancillary data such as unix credentials (See GUnixCredentialsMessage) and Unix file descriptions (See GUnixFDMessage).

Functions

                                GSocketControlMessage *message);

Attaches message as metadata in a GstNetControlMessageMeta to buffer .

Parameters
