Hello All,
The documentation leaves the Network section of the API as "To be written..."
I've looked at the header file, and it may be straightforward to call, but...
Does anyone know how to properly invoke this part of the API?
Is it correct to assume that the point of the network API is to create a
"virtual" network interface that I can treat like any other NIC
(unidirectional, of course)?
My goal is to receive multicast packets using a Skystar 2 DVB-S card (rev 2.6),
using standard multicast join and UDP receive calls.
The dvb_net_if structure has the following fields:
__u16 pid; // This is obvious
__u16 if_num; // Don't know exactly what goes here???
__u8 feedtype; // This is either 0 (MPE) or 1 (ULE)
For example, does the following code snippet the proper way to go about this?
struct dbv_net_if dni;
int sd;
dni.pid = 3022; // My MPEG2 PID
dni.if_num = 0; // ???
dni.feedtype = DVB_NET_FEEDTYPE_MPE;
sd = open("/dev/dvb/adapter0/net0", O_RDONLY);
ioctl(sd, NET_ADD_IF, &dni);
Now, do I read packets from /dev/dvb/adapter0/net0 using my sd descriptor?
Or do I at this point open a standard UDP socket and start listening for
packets from the satellite interface?
Any help in clearing my basic confusion would be much appreciated.
Thank-you!
Bob
