4.5. 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;
      struct mutex remove_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.

remove_mutex

mutex that avoids a race condition between a callback called when the hardware is disconnected and the file_operations of dvb_net.

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.
