The implementation (in svl/source/svdde/ddedata.cxx) returns any of:
* {CF_TEXT=1, CF_BITMAP=2, CF_METFILEPICT=3} from the Windows API;
* the return value of Windows API's RegisterClipboardFormatW, which is UINT from
the Windows API (i.e., 32-bit unsigned int);
* a enum SotClipboardFormatId value, whose underlying type is sal_uInt32.
So the natural choice is sal_uInt32 here. (Windows API's UINT would also do,
but cannot be used in include/svl/svdde.hxx, which is used on all platforms.)
That in turn shows that DdeService's aFormats and HasCbFormat should also use
sal_uInt32. (And then, simplify some of the std algorithms use in
svl/source/svdde/ddesvr.cxx.)
