What is the deal on sprintfs return value?

What's the deal on sprintf's return value? Is it an int or a char *?

The Standard says that it returns an int (the number of characters written, just
like printf and fprintf). Once upon a time, in some C libraries, sprintf returned
the char * value of its first argument, pointing to the completed result (i.e. analogous
to strcpy's return value).
