/* The following is an implementation of pthread_atfork that
 * does absolutely nothing when nvidia is being used for rendering.
 *
 * This is needed because nvidia adds atfork handlers which are not
 * async-signal safe and contain minor data-races which can lead to
 * unexpected crashes.
 *
 * For example from valgrind's helgrind
 *
 * ==17309== Possible data race during write of size 1 at 0x3EEEC5E0 by thread #27

What is Vulkan

Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Vulkan targets

Vulkan targets high-performance realtime 3D graphics applications such as games and interactive media across multiple platforms providing higher performance and lower CPU usage.

Working around offsetof limitations in C++:

There is sometimes a situation in which one needs to get the relative offset of a structure field, common examples of this include serialization frameworks which aid to serialize objects, vertex attributes for rendering (D3D, GL.), etc.

The most common technique for getting this information is through the offsetof macro defined in stddef.h. Unfortunately using the macro in C++ comes with a new set of restrictions that prevent some (subjectively valid) uses of it.

Achievement	Engine/Game	Why it's bad
storing world space positions in gbuffer	STALKER, F.E.A.R.	Depth buffer can be used to derive position saving a lot of memory bandwidth
uploaded texture upside down	Various engines, mostly Quake derived.	Difficult to debug with tools like apitrace, nsight, pix, renderdoc, etc
