2.5. Digital TV Network kABI¶

struct dvb_net: describes a DVB network interface

Definition

struct dvb_net {
  struct dvb_device *dvbdev;
  struct net_device *device[DVB_NET_DEVICES_MAX];
  int state[DVB_NET_DEVICES_MAX];
  unsigned int exit:1;
  struct dmx_demux *demux;
  struct mutex ioctl_mutex;
};

Members

dvbdev: pointer to struct dvb_device.
device: array of pointers to struct net_device.
state: array of integers to each net device. A value different than zero means that the interface is in usage.
exit: flag to indicate when the device is being removed.
demux: pointer to struct dmx_demux.
ioctl_mutex: protect access to this struct.

Description

Currently, the core supports up to DVB_NET_DEVICES_MAX (10) network devices.

int dvb_net_init(struct dvb_adapter *adap, struct dvb_net *dvbnet, struct dmx_demux *dmxdemux)¶: nitializes a digital TV network device and registers it.

Parameters

struct dvb_adapter * adap: pointer to struct dvb_adapter.
struct dvb_net * dvbnet: pointer to struct dvb_net.
struct dmx_demux * dmxdemux: pointer to struct dmx_demux.

void dvb_net_release(struct dvb_net *dvbnet)¶: releases a digital TV network device and unregisters it.

Parameters

struct dvb_net * dvbnet: pointer to struct dvb_net.
