Macro Definition Documentation

#define _DEBUG_NEW_REDEFINE_NEW   1

Macro to indicate whether redefinition of new is wanted. If one wants to define one's own operator new, or to call operator new directly, 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 _NEW_REDEFINED
#   ifdef DEBUG_NEW
#     define new DEBUG_NEW
#   endif
#   undef _NEW_REDEFINED
# endif

Definition at line 70 of file debug_new.h.

#define _DEBUG_NEW_TYPE   1

Macro to indicate which variant of DEBUG_NEW is wanted. The default value 1 allows the use of placement new (like new(std::nothrow)), but the verbose output (when new_verbose_flag is true) looks worse than some older versions (no file/line information for allocations). Define it to 2 to revert to the old behaviour that records file and line information directly on the call to operator new.

Definition at line 85 of file debug_new.h.

#define DEBUG_NEW   __debug_new_recorder(__FILE__, __LINE__) ->* 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.
