I have a C + + OpenCV code that I need to convert to C. But I could not find a guide to check what I want instead, if you see any other problem in your code, can you tell me?
cvScalar, cvNamedWindow, cvSmooth
Use instead>

Here are the errors:

The constructions you mention are present in C under their name. You can continue to use them using C API instead of C ++ API.
Edit: Note that the implementation of C is not the default argument you will need to provide all the arguments on each function, even if Only you are sticking to the default ones
See for more information.
