It’s important to at least know that these concepts exist and understand some basic idea behind them, before writing the driver. The Driver’s “main” After the compiler is setup with the appropriate options, it’s probably good to start thinking about the entry point to a driver. Companies LOVE "fresh-outs"/"new grads" because they know you won't ask for much money and will be willing to do WHATEVER THEY ASK including long stints overseas if required. useful reference This tutorial will describe how to create a simple device driver, dynamically load and unload it, and finally talk to it from user mode.

The information in this course will work with any major Linux distribution. Device Driver Download user mode[edit] Device drivers, particularly on modern[update] Microsoft Windows platforms, can run in kernel-mode (Ring 0 on x86 CPUs) or in user-mode (Ring3 on x86 CPUs).[5] The primary benefit of running This is the “default” type of executable that is made when specifying “NATIVE” in the same way “WinMain” and “main” are found when the linker is creating an application.
