I feel that if C had tagged unions and a little sugar you could write non magical generic functions in C. Non magical meaning unlike C++ etc instead of the compiler selecting the correct function based on the arguments the function itself can tell and handle each case.

Basically you can write a function that takes a tagged union and the compiler will passed the correct union based on named arguments.

   int ret = foo(.slice = name);

   int ret = foo(.src = str, .sz = strlen(str));
