You may encounter an error code pointing to directx with c. There are several ways to solve this problem, and that’s what we’ll talk about now.
Windows desktop application with C ++ and DirectX A Windows desktop application with DirectX is simply an application developed using native C ++ and DirectX APIs.
The Open Watcom c / c ++ compiler comes with sample DirectX applications in C ++ and C. Both work. This is WATCOM samples directx cpp and therefore WATCOM samples directx c in OW 1.9.
You can use DirectX in C. It has special macros to make the COM interface easier to use.
Just a warning, C is incompatible with the “light” being used is compatibleSTU COM. in the DirectX API.
Note that the C ABI for returning structures is different from C ++; H. if D3D12 has APIs that have a tax return that cannot be called, they cannot be called from C. returns a small structure in a backup, while the C ++ interface returns a reference battery with.
We saw this in the Direct2D API when trying to add C # interop signatures, and were very surprised to find that the C and C ++ ABIs differ for most of the same conventions from call.
Just a word of warning: C is not fully compatible with the “lightweight” COM interop used by the DirectX API.

Note that the C ABI for returning structures is different from the meaning of C ++, if D3D12 has APIs that return structures, they cannot be synchronized C. return a small structure to their registry, while the C ++ interface returns a reference to the stack.
The Microsoft Component Object Model (COM) is an object-oriented development model used by several technologies, including the most important part of the DirectX API. For this reason, you (as a DirectX developer) inevitably use COM when programming DirectX.
We discovered this in the Direct2D API when trying to write C # interop signatures, and were very impressed that the C and C ++ ABIs differed to create the same convention forchallenges.
