how, for example, a function like ctime() works. It looks like it allocates

I think many older functions are written to return a pointer to one of
their local variables. inet_addr is one example I can think of off the
top of my head. It's not really allocating on every call. It just writes
to its local buffer and returns the pointer to it.
