Hi, I see that @_documentation(visibility: ...) is available and I have it working for swift source files when using DocC. My question is how to do the same thing for c source (the .h header files specifically)? I haven't been able to find a way to exclude methods or variables in c code from the documentation DocC creates. I'd also be fine with excluding c header files entirely from DocC. Is this available? If so, how could it be done? Mark
