The C++ Standard Doesn't Permit Overloading new and delete? In the 13.5 of The C++ standard (ISO/IEC 14882, 1998), I cannot find the specification on overloading the operators new and delete; however, many C++ books including "C++ Primer" say that the operators new and delete can be overloaded. I wonder if this has definitive specification? Who can tell me? Many thanks to those who answer. [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Even I thought that new and delete cannot be overloaded, so if you got somthing please do tell me........ [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

See 3.7.3.1, and in particular 5.3.4 p8 (and subsequent paragraphs). 12.5 is also useful. You need to search for "operator new". Quote: I wonder if this has definitive specification? Well clearly the standard document is definitive for standard C++. However it requires a signficant level of expertise to interpret.

I wonder if this has definitive specification? Who can tell me? The new and delete operators CAN NOT be overloaded. There are functions called "operator new" and "operator delete" but they are unfortunate names. Rather than being the implementation of those operators, they are the memory allocation functions that new/delete calls. There's too much happening behind the scenes of object creation that you can't implement even if you wanted to do so. Your stuck with playing with the allocation functions and the constructors themselves. [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
