Find a device that matches the search criteria given by this functions's parameters.

Parameters

dvb pointer to struct dvb_device to be used
adapter Adapter number, as defined internally at the Kernel. Always start with 0;
num Digital TV device number (e. g. frontend0, net0, etc);
type Type of the device, as given by enum dvb_dev_type;

Returns

returns a pointer to a struct dvb_dev_list object or NULL if the desired device was not found.

Return data about a device from its sysname.

Parameters

dvb pointer to struct dvb_device to be used
sysname Kernel's name of the device to be opened, as obtained via dvb_dev_seek_by_adapter() or via dvb_dev_find().

Returns

returns a pointer to a struct dvb_dev_list object or NULL if the desired device was not found.
