[fpc-devel] Widestrings in win32
Hi, It seems that CG plans to implement an non BSTR widestring type for win32: http://groups.google.ch/group/borland.public.delphi.non-technical/msg/7caeced42f1934a4?hl=en; The introduced string handling for the Unicode VCL is equivalent to the string handling in MSEgui BTW.

I would appreciate very much. If you can do so, I could restart the testing
and debugging of FPC 2.2.
I made the change, could you please test for any problems, as we are
really close to 2.2.0.

Something like this?
Note that casting pointers to signed values is often a bad idea, since
the virtual address space on a 32-bit system is often 3 gigabytes, i.e.
pointers can have values between $8000..$c000. A signed type
causes trouble in pointer value comparisons (like if pq then).
In Free Pascal there already exist two types ptrint and ptruint (signed
and unsigned) for this purpose, you might want to recycle them especially
as many people are currently using constructions like:
{$ifndef FPC}
type ptruint=longword;
{$endif}
... in order to be able to get their code to work on Win64 using FPC; this
will make it easier for people to switch back to Delphi for 64-bit
development when it is ultimately released.

Widestring remains the COM compatible one AFAICS, and there is a new UnicodeString that maybe has ref counting features. I quote: WideString will remain a BSTR for use in interoperating with COM. The good thing is that the conversions between BSTRs and UnicodeStrings is much more simple and straight forward...

You mean to let it compile on delphi (win32), while porting the code to
win64 using FPC. It would compile on FPC anyway.

This is an emergency measure; incompatible widestrings are preferable over broken widestrings, which totally blocks the usability of FPC 2.1+ for for Martin. I am fully aware of the consequences; all code which does something with OLE will not function.

When assigning two records/arrays/whatever type containing a widestring to another the compiler: * Two pointers are pointing to the same widestring * One widestring is lost in memory as a memory leak Florian has written a proper fix. Good, so now we are COM compatible again? This because I am planning to port the OpenOffice bridge. However that uses COM _and_ packages.
