something like fdopen(_open_osfhandle(handle, _O_BINARY), "rb"). Check
MSDN and mingw headers for details. Note that it doesn't work for
random HANDLEs, only for HANDLEs to things that can be read and
written with ReadFile and WriteFile I assume. File and (anonymous)
pipe handles, maybe console handles.

No way... just like you can't fwrite() to a file descriptor on POSIX.
(But note that the likeness is not 100%; on Windows the "file
descriptors" (the small integers that open() etc return and use) are
just indexes into a table specific to the C library instance, the
kernel (or the Win32 subsystem) knows nothing of them.)
