ID3D11Device::GetExceptionMode

DX11 vtable[42] → UINT

ID3D11Device::GetExceptionMode is a method of the COM interface ID3D11Device in Direct3D 11. Its function pointer sits at vtable index 42 — 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 no parameters and returns UINT.

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.
