IDirect3D9Ex::EnumAdapterModes

DX9 vtable[7] → HRESULT

IDirect3D9Ex::EnumAdapterModes is a method of the COM interface IDirect3D9Ex in Direct3D 9. Its function pointer sits at vtable index 7 — 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 4 parameters (adapter_idx, format, mode_idx, mode) 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.
