CodeWeavers

Description

Windows: Win32, Vulkan, DirectX 8-12, d3dcompiler, dinput, xinput, windows.gaming.input, mmdevapi, mshtml, media foundation, quartz, nvapi, crypt32, ...

Linux: Vulkan, OpenGL, futexes, eventfd, hid, evdev, X11, PulseAudio, GNUTLS, gstreamer, SDL, ...

Some of those APIs are implemented on the Windows side using other already implemented APIs. The rest has to cross the Windows<->Linux boundary.

I'll explain what is implemented on top of what and how we cross the boundary when necessary, focusing on APIs used by games.
