Yes I had noticed that and I was trying to see what I can do.
My problem is that I replace the // FIXME with a printk() and it does not get
called
How is it supposed to work?
I open /dev/dvb/adapter0/dvr0, I get back a file descriptor and the I call the
ioctl with that file
descriptor.
This code comes from gnutv_data.c plus my additional code
// open dvr device
dvrfd = dvbdemux_open_dvr(adapter_id, 0, 1, 0);
if (dvrfd < 0) {
fprintf(stderr, "Failed to open DVR device\n");
exit(1);
}
if (buffer_size > 0)
{
int res = dvbdemux_set_buffer(dvrfd, buffer_size);
if (res < 0) {
fprintf(stderr, "Failed to set ring buffer size\n");
exit(1);
}
}
Regardless of what is implemented or not, would that be correct?
