Subject: wchar_t and XMLCh
I know this
question has probably been discussed before, but I just want to see if
there are any new solutions.
Basically I need
to convert the XMLCh* to a std::wstring and vice versa. In Xerces, XMLCh is
typdef-ed to unsigned short (2 bytes). Under win32, there is no need for
conversion since wchar_t is also typedef-ed to unsigned short. In
Solaris/Linux/VMS, however, wchar_t is typedef-ed to unsigned long (4 bytes),
so the conversion seem to be inevitable.
My question is:
Does Xerces implementation requires that the size XMLCh to be 2
bytes? if I change the typedef of XMLCh to wchar_t and recompile the
xerces, would it work? I know the answer is probably no, but I just want
to make sure. Of course the memory usage will be doubled if we change the
XMLCh to 4 bytes, but that is not a concern for me.
If the conversion
is inevitable, does xerces provide some helper classes/functions to do
that?
Any suggestions
are greatly appreciated.
