How can I convert a file descriptor from Cygwin openat() to Win32 file HANDLE?
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.
