Greetings, I have a struct in a header file. And I would like to have some of this struct member fields to be constant, in case if this header file is included from some particular Cpp files. Motivation for this is to avoid some silly programmer errors by accidentally writing to this variable, when developer is not supposed to do that. I guess that it is possible to catch these errors already at the compile time with a const keyword.
I already have approach, but I am not quite sure whether it is safe(especially regarding the compiler optimizations). Below are uplaoded files. In this case util.cpp is not allowed to edit S.y contents, while rw.cpp is allowed to do that. File h.hpp contains the struct which is customized at the preprocessor execution time by looking at the READONLY define. If this is not safe, are there any other approaches? I am afraid that compiler might optimize out something. Assumption is that other threads will not touch this member.
