how, for example, a function like ctime() works. It looks like it allocates char[25] every time it's called without ever freeing the memory. Wouldn't it be more correct to take a pointer to an output parameter and let the calling program deal with the memory allocation?
Boris:ctime has a statically-allocated buffer to contain the result. If you want to keep a result across calls to ctime, you will need to save the result in your own string buffer. Don't attempt to free the buffer pointer returned by ctime.
