Re: [ros-dev] GDI_TABLE_ENTRY structure

[Timo Kreuzer]

The structure is completely binary and source compatible to what we have
so far, wich is (now, after my fix to gdiobj code) compatible to windows.
We can simply replace the struct and everything else could stay the same.
It just gives us the possibility to access single fields without using
masks and bitshifts.
And it has the Fields TypeLower in the table entry type and Upper in the
handle type. This allows quick comparison.
    if (Entry->TypeLower == Handle.Upper)
instead of
    if ((Entry->Type << GDI_ENTRY_UPPER_SHIFT) == GDI_HANDLE_GET_TYPE(hObj))
