In general, this can be done with:
     hFile = (HANDLE) _get_osfhandle (int fd);

That works for simple cases such as disk file descriptors. I've learned 
one can't always depend on it because Cygwin can use several handles for 
a specific file or other object in certain situations, which I'm not 
going to list here because I don't know them all.

Try that and see if it works for your case.
