You mean file descriptor, not "int fh". "File handle" usually means a
FILE or FILE pointer. Anyway, file descriptors are a Unix feature
emulated by many C libraries and not by Win32. The VC++ library
provides the function _get_osfhandle which returns the underlying Win32
file handle for a file descriptor. Other C/C++ libraries for Windows
may provide similar functions.
