Re: Wireless API
Hi Adrian That is OK, I have download the source code of Wifimgr, it use ifconfig. I was using ifconfig wlan0 scan, it was to slow to display info, but in the Wifimgr code they use ifconfig -v wlan* list scan and ifconfig wlan* list scan. I also found wifimgr calculate S:N to find the percentage of the connection, it is (S - N) * 4. I have also read further ifconfig manual, I suppose ifconfig will be a kind of API for my work.

Re: Wireless API
I'd rather that the ioctl API be used, rather than the output of 'ifconfig'. It's likely about time the ioctl API was turned into a library for userland to use. That way it could be imported into python/etc via C bindings.

Re: Wireless API
The wireless API used to be the same as what's in Linux. So, in theory, we could just use anything that used Linux wireless extensions. Save, of course, the API drift. So, you could just write a full wireless manager that used the ioctl API for the basic manipulation of the VAP (eg link status, current association state, etc) and the wpa_supplicant socket API for talking to the supplicant for the scan list, telling it which SSID to try associating to, etc. -adrian On 15 October 2013 09:39, Sam Fourman Jr. sfour...@gmail.com wrote: On Oct 15, 2013 12:26 PM, Kris Moore k...@pcbsd.org wrote: On 10/15/2013 11:15, Adrian Chadd wrote: Well, up until now the interactions have all been via the ioctl API or the ifconfig command.

As an example the network manager in Gnome hasn't been ported for years, and I belive the largest part of the reason is lack of an API. The importance of this really can't be underestimated. Is there a formal way, to propose a project to the FreeBSD foundation?
