ID3D11DeviceContext::DrawAuto
DX11 vtable[38] → void
ID3D11DeviceContext::DrawAuto is a method of the COM interface ID3D11DeviceContext in Direct3D 11. Its function pointer sits at vtable index 38 — 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 void.
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.
