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
.
