/*
|
||
|
|
* C mirror of NvFBC's ToSys interface. The vendor header
|
||
|
|
* third_party/NvFBC/nvFBCToSys.h declares INvFBCToSys_v3 as a C++ abstract
|
||
|
|
* class (vtable of 5 pure-virtual
|
||
|
|
* __stdcall methods). We do NOT edit the vendor header; instead we replicate its
|
||
|
|
* single-inheritance vtable ABI as a COM-in-C interface so the producer stays
|
||
|
|
* pure C. Slot order MUST match declaration order in nvFBCToSys.h:
|
||
|
|
* 0 NvFBCToSysSetUp
|
||
|
|
* 1 NvFBCToSysGrabFrame
|
||
|
|
* 2 NvFBCToSysCursorCapture
|
||
|
|
* 3 NvFBCToSysGPUBasedCPUSleep
|
||
|
|
* 4 NvFBCToSysRelease
|
||
|
|
* On x64 (mingw/MSVC) `this` is the implicit first integer argument; __stdcall
|
||
|
|
* is a no-op for x64 so a plain pointer arg matches the vtable slot.
