Yes it's probably only really useful for parallel code, but it's always nice to make constant things const.

  Why use "const int" there instead of #define? Far fewer issues with linkage and use in multiple files with #define.

    No. If it's const it is static be default. This is the kind of shit that makes the windows api the royal pain in the ass it is.

      >If it's const it is static be default. If it's const at the file scope it's notably NOT static in the 'visible in the file scope only' sense of the word. Try it, declare a const int at file scope in a C file and use it in a different C file with a extern prototype.

    Because you can do this at runtime. I might have a different value everytime I call the function but this means that inside the fucntion the compiler knows the value can't change

      Why ever use const at a file scope level. That's what I mean. #defines work SO much better there. Especially if being used outside the file.
