+- Netlink Library (libnl) [documentation](https://www.infradead.org/~tgr/libnl/doc/core.html)
+- Minimalistic Netlink Library (libmnl) doxygen [documentation](https://www.netfilter.org/projects/libmnl/doxygen/) and [code](https://git.netfilter.org/libmnl/)
+- nl80211 [header file](http://lxr.free-electrons.com/source/include/uapi/linux/nl80211.h)
+- iw [code](http://git.kernel.org/?p=linux/kernel/git/jberg/iw.git)
+- wavemon [code](https://github.com/uoaerg/wavemon)
+- wpa_supplicant and hostapd [code](http://ftp.tku.edu.tw/NetBSD/NetBSD-current/src/external/bsd/wpa/dist/src/drivers/driver_nl80211_scan.c)

+And finally the implementation `wifi-scan.c` has some comments that may be usefull to you.
