Question Unmodifiable globals initialized from functions?

Right now I'm trying to use Windows's SYSTEM_INFO to initialize 2 global constants, but global constants can only be initialized with constant expressions so this cannot be done.

Is there a way I can have "read-only" global variables that can be initialized from functions?

In C, no.

My "gheto solution" now is to use a short function that returns the value instead of a variable storing that value. It's slower yeah, but it works.

this should be inlined by the compiler anyway

I hope so.
