I want to write unit tests for my self-written standard c library.
So, i want to compare output of functions <ctype.h>::tolower amd my tolower implementation. How can i do it without renaming my functions?

          I think you could add a define at the start of the header of your library like this :
          #define tolower my_tolower
          Adding this pre-processor command will automatically renamed your function temporary in your files, after that in the main you only have to call my_tolower
