Yeah, I use that all the time. I think I use it in a different way though. I have projects with C, C++ and other languages. The C and C++ get compiled and linked together, and so there are some considerations for those files that don't apply to anything else. So I mean C files and C++ files, but not as if they were the same language.

Yeah that's completely fair and makes sense to me. I just know I've come across stuff where people are talking about it like they're the same language. This seems to be especially prevalent in windows development where the C support is pretty poor in comparison and tends to kinda be lumped into into C++.

Projects for Apple platforms usually also use .h, where it could mean anything from C/C++ to Objective-C/C++.

In practice, Clang handles mixed C/C++/Obj-C codebases pretty well and determining the language for a header never really felt like an issue since the API would usually already imply it (declaring a C++ class and/or Obj-C class would require the corresponding language to consume it).

If a C++ header is intended to be consumed from C, adding the usual #ifdef __cplusplus extern "C" {... should alleviate the name mangling issues.

Yeah, I was ignoring apple platforms because Objective-C doesn't even have its own header extension as an option. Also not all C headers do extern stuff...and it doesn't fix 100% of compatibility problems when you do that anyway. Also I'm not really talking about it from a compiler perspective, I'm talking about it from an organization and human perspective. I know compilers generally don't care...which is exactly how we ended up in this predicament.
