Wi-Fi peer-to-peer API on Mac OS X

The OS X AirDrop feature allows a direct Wi-Fi connection with the nearest Mac, which is simultaneously with any Wi-Fi AP connection. He said differently that he uses Wi-Fi IBSS (aka ad hoc) or Wi-Fi Direct.

Is there an API (possibly undocumented driver commands) for controlling parallel Wi-Fi P2P?

I believe AirDrop uses IBSS since it runs on a Mac prior to Wi-Fi Direct and uses TLS, which is necessary because IBSS provides only WEP. But maybe it uses Wi-Fi Direct if both nodes support it?

Alternatively, what are the best resources for undocumented OS X APIs?

According to here , AFP is the most common network protocol for the Apple Macintosh. This may be the documentation you are looking for. Not sure if this "AirDrop" is just an extension of this feature, so you can use Netatalk, Jaffer or another third-party api .

This looks promising: https://serverfault.com/a/54256

Typically, if you look into system libraries, you may find class-dump useful ... You can also use nm to output characters from libraries / frameworks.

I believe Wi-Fi Direct is AirDrop's requirement, according to MacWorld here , although the end of 2008 seems a bit early for WiFi Direct.
