while porting the S2api to userspace I came accross the S2-API definition itself
#define FE_SET_PROPERTY _IOW('o', 82, struct dtv_properties)
#define FE_GET_PROPERTY _IOR('o', 83, struct dtv_properties)
while looking at this, FE_GET_PROPERTY should very likely be _IOWR
in dvb-frontend.c:
----
if(cmd == FE_GET_PROPERTY) {
tvps = (struct dtv_properties __user *)parg;
dprintk("%s() properties.num = %d\n", __func__, tvps->num);
dprintk("%s() properties.props = %p\n", __func__, tvps->props);
...
if (copy_from_user(tvp, tvps->props, tvps->num *
sizeof(struct dtv_property)))
----

Markus
