I'm writing a library to use in my projects. In it, I was hoping to wrap the c standard library in my library's namespace and a cstd namespace to avoid having its functions in the global namespace. However, from a previous question I asked and from what I've tested, I can't just #include everything in a namespace. Is there any way to do this?
I doubt it, unless you wanted to rewrite everything.
The C language itself has no concept of namespaces, so everything the C standard library uses must rely on the fact that whatever it is looking for resides in the global namespace.
If you simply wrapped a namespace around your #includes, the compiler wouldn't be able to find anything because it wouldn't know what namespace to look in.
