w32 is a wrapper for a number of Windows APIs for the Go Programming Language.
This library has no other dependencies and you need no C-compiler, it is written in pure Go. Some function signatures have been adapted to make them work in Go, e.g. functions that take a pointer to an array and a count of items in C will now simply accept a slice in Go.
If you miss any Windows API functions, just write an issue or create a pull request, the Win32 API is very large and has many rarely used functions in it so this wrapper is supposed to grow as needed by the Go community.
