You probably want to look elsewhere in your API.  An apache request isn't
a file, and has no file descriptor.

If your library is designed to be usable in non-file applications,
it'll offer some mechanism for plugging in your own I/O functions.

If not, you could perhaps try some ugly hack: create some bucket of
file-compatible type for it to write to.
