Tiny utility to print the Wi-Fi IP address, SSID and signal strength in percent of a given interface.

Useful for integrating into scripts showing this information, eg. i3blocks.

Not if your stupid proprietary Wi-Fi driver (cough, cough Broadcom's wl) only allows access to this information as root through the usual tools.

You need libnl and CMake.

mkdir build
cd build
cmake ..
make install

print-wifi-nl wlp3s0

If it was successful, it returns status 0 and you get a tab-separated IP address, SSID, and signal strength in percent.

If it was unsuccessful, or the interface is down, you get status 1.

It's taken from the brilliant guys behind i3status.

Thanks for figuring out how to solve this problem with the libnl library! I've just taken the code concerning Wi-Fi and adjusted it for my needs. I love i3wm but I prefer to use i3blocks to feed my status bar.
