ID3D11Device::CheckCounter

DX11 vtable[32] → HRESULT

ID3D11Device::CheckCounter is a method of the COM interface ID3D11Device in Direct3D 11. Its function pointer sits at vtable index 32 — the zero-based slot in that interface's virtual method table, counted from QueryInterface and including every entry inherited from a base interface. It takes 9 parameters (pDesc, pType, pActiveCounters, szName, pNameLength, szUnits, pUnitsLength, szDescription, pDescriptionLength) and returns HRESULT.

COM methods are reached through that table rather than by an exported name, so the slot index is what a wrapper, an interface hook or a disassembly listing has to resolve against. The parameter order and types below are the ones this interface declares.
