ID3D11VideoDevice::CreateAuthenticatedChannel

DX11 vtable[5] → HRESULT

ID3D11VideoDevice::CreateAuthenticatedChannel is a method of the COM interface ID3D11VideoDevice in Direct3D 11. Its function pointer sits at vtable index 5 — 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 2 parameters (ChannelType, ppAuthenticatedChannel) 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.
