define for overloaded new

[Alex Vinokur]

Hi,

I need to overload new operator.
Hoever, there is some problem with new (std::nothrow).


Is there any way to resolve the problem without '#undef new' below?



--------------------------------------
#define NEW new(size, __FILE__, __LINE__)
#define new NEW



int main()
{
char* p1 = new char; // Actiually new(size, __FILE__, __LINE__)


#ifdef new
#undef new
char* p2 = new (std::nothrow) char;
#define NEW
#endif
}
--------------------------------------

No, you cannot override any operator new in places where this macro is
visible. You have to choose one or the other.

......
char* p2 = new (std::nothrow) char;
#define new NEW // here was a typo in original post
