A client of mine claims to have a good reason for wanting to know the size of the memory being deallocated by the global operator delete, and when he asked me why there was no global version like the class version taking a size_t, I found that I had no idea why such a version is missing. Is there a good technical basis for the omission? Thanks, Scott --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
