IDirect3DDevice9::DrawIndexedPrimitiveUP
DX9 vtable[84] → HRESULT
IDirect3DDevice9::DrawIndexedPrimitiveUP is a method of the COM interface IDirect3DDevice9 in Direct3D 9. Its function pointer sits at vtable index 84 — 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 8 parameters (primitive_type, min_vertex_idx, vertex_count, primitive_count, index_data, index_format, data, stride) 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.
