// This file provides basic Windows implementation of Linux specific functions
// used in the dump1090 project. This allows dump1090 to be compiled and debugged
// using Microsoft Visual C++ 6.0
//
// Note that not all functions actually provide equivalent functionality to their
// Linux equivalents. They are simply stubs to allow the project to compile.
