The expression to return the caller address. print_position will later on use this address to print the position information of memory operation points.

Definition at line 110 of file debug_new.h.


Macro to indicate whether redefinition of new is wanted. If one wants to define one's own operator new, to call operator new directly, or to call placement new, it should be defined to 0 to alter the default behaviour. Unless, of course, one is willing to take the trouble to write something like:

 # ifdef new
 #   define _NEW_REDEFINED
 #   undef new
 # endif

 // Code that uses new is here

 #   ifdef DEBUG_NEW
 #     define new DEBUG_NEW
 #   endif
 #   undef _NEW_REDEFINED
 # endif

Definition at line 96 of file debug_new.h.

#define DEBUG_NEW   qx::memory::__debug_new_recorder(__FILE__, __LINE__, __FUNCTION__) ->* new

Macro to catch file/line information on allocation. If _DEBUG_NEW_REDEFINE_NEW is 0, one can use this macro directly; otherwise new will be defined to it, and one must use new instead.

Definition at line 122 of file debug_new.h.


Macro to indicate whether placement delete operators are supported on a certain compiler. Some compilers, like Borland C++ Compiler 5.5.1 and Digital Mars Compiler 8.42, do not support them, and the user must define this macro to 0 to make the program compile. Also note that in that case memory leakage will occur if an exception is thrown in the initialization (constructor) of a dynamically created object.
