Sending raw packets over Wi-Fi on Linux (C / C ++)

Question

I would like to experiment with C / C ++ software to send raw 802.11 packets from my WiFi (possibly with the ability to change the MAC address, etc.).

Basically, I would like to implement something very similar to this ethernet code example , but really on Wi-Fi instead of being over Ethernet.

Where to begin? Are there any documents / examples you can point me to?

Thank!

Ps. An interesting library that allows you to scan WiFi is here
