    c.user, even if what you proposed were absolutely legal, what advantage would it provide? You would require that users of your comparator cast the function pointer for each use, whereas with the canonical version they would just need to provide the function pointer to the comparator.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Oh, I can sort this functions
    qsort and strcmp are irrelevant

    I can have more compare functions, when you have more than ten or twenty functions it is easier to look only for their headers (to know what is they do), and if you have a compare function which longer than one line or five lines it will save your time

    example with the function which irrelevant to qsort
