There are many Wifi device on market such as PC, smart phone, smart watch wifi dongle for which c code is written.
What are common things in all devices that should be know when writing code. I am looking for common things I did research but i didn't get much help. Maybe someone can share some thought having experience on WiFi coding
At what level?
In normal user space, WiFi == LAN and you don't give a damn what the underlying transport is.

All the WiFi implementations provide you with the same API.
If you're deep in kernel driver space bit-banging on some RF chip, then you have a whole host of problems to solve in very implementation specific ways.
There might be some sample code from the device manufacturer, but after that, you're on your own.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
