Returns an integer indicating the new handler mode set by _set_new_mode for malloc.

      int _query_new_mode(  

Returns the current new handler mode, namely 0 or 1, for malloc. A return value of 1 indicates that, on failure to allocate memory, malloc calls the new handler routine; a return value of 0 indicates that it does not.

The C++ _query_new_mode function returns an integer that indicates the new handler mode that is set by the C++ _set_new_mode function for malloc. The new handler mode indicates whether, on failure to allocate memory, malloc is to call the new handler routine as set by _set_new_handler. By default, malloc does not call the new handler routine on failure. You can use _set_new_mode to override this behavior so that on failure malloc calls the new handler routine in the same way that the new operator does when it fails to allocate memory. For more information, see the operator delete and operator new functions in C++ Language Reference.
