It’s wrappers all the way down

  Dear my... this is way leaner in C. return strrchr(str,',')+1; There are just a handful of branches unless your library goes nuts with vectorization. If you want to handle three forms of broken input: if(!str) return NULL; str = strrchr(str,','); if(!str) return NULL; if(!*++str) return NULL; return str;

    It's only leaner in C if you know that the caller doesn't need a freshly-allocated string, and isn't going to free the pointer that you return.

      add a strdup() That is still far fewer layers of gunk, not even counting whatever may underlie the non-C strings.

        Surely you mean strndup, since you're keeping careful track of the correct length of your strings to prevent buffer overflows.
