hi all,
is there a possibility to determine in which wlan mode my card/driver
currently works?
like an ioctl()-call or sth... ? is it also possible to fetch wlan
statistics (rx/tx) via ioctl()?
if yes, which params are neccessary?
big thx & nice weekend

You might be able to get it using ioctl(SIOCGIWNAME); this returns a
string describing the interface, but some drivers just return the
driver name. The parameter is a pointer to a "union iwreq_data"
(defined in linux/wireless.h); the name field will be filled by the
ioctl.

You can get packet/byte counts for any interface from /proc/net/dev.
