DOS ain't dead

HX and memory mapped writable files. (DOSX)

Hi all,

I just tested memory mapping to write a file with HX and the file is either not created or not written to (I don't recall) when the map is not explicitly closed by the application. Is that a bug in HX?

More explicitly, using CreateFile(), CreateFileMapping() and MapViewOfFile() for writing, the file isn't written without
UnmapViewOfFile( map );
CloseHandle( mapping );
CloseHandle( f );

I just added all three since and so I do not know if only one or all three are needed.

Wine creates the file without this explicit closing. I did not test on NT itself.
