C++ programmers who define D3D_OVERLOADS can use the extensions documented here to simplify their code in Direct3D Immediate Mode applications. The use of D3D_OVERLOADS was introduced with Microsoft® DirectX® 5.0. This section is a reference to the D3D_OVERLOADS extensions.
These extensions must be defined with C++ linkage. If D3D_OVERLOADS is defined and the inclusion of D3dtypes.h or D3d.h is surrounded by extern "C", link errors result. For example, the following syntax would generate link errors because of C linkage of D3D_OVERLOADS functionality:
#define D3D_OVERLOADS extern "C" { #include <d3d.h> };
The D3D_OVERLOADS extensions can be organized into the following groups:
