/* The purpose of this file is to abstract the differences between the Windows
|
||
* C ABI for D3D12 and the Linux ABI. Essentially, for class methods that return
|
||
* structures, the MSVC C++ ABI specifies that they are always called with the return
|
||
* structure allocated by the caller, and passed as a hidden second parameter,
|
||
* after "this". But the C compiler doesn't apply that automatically to the C
|
||
* equivalent definition of the method, and so that ABI needs to be explicitly
|
||
* embedded in the C function signature. For Linux, no such ABI difference between
|
||
* C and C++ exists, and so C callers should use the same signature as C++.
