PRB: Errors Generated Overloading Operator New []

• Microsoft C/C++ for MS-DOS, version 7.0
• Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, 1.52
• Microsoft Visual C++ 32-bit Edition, versions 1.0, 2.0, 4.0, 4.1, 4.2, 5.0

SYMPTOMS

The September 1994 ANSI C++ Draft specifies that it is possible to overload the new [] operator. However, the Microsoft C/C++ compilers included in the Microsoft products listed above do not support this feature. Microsoft C/C++ version 7.0 and Visual C++ up to version 5.0 will generate the following error message:

   error C2092: array element type cannot be function

   error C2039: 'new[]' : is not a member of '`global namespace''
   error C2660: 'new[]' : function does not take 1 parameters

STATUS

This behavior is by design.

MORE INFORMATION

The source code below can be used to illustrate how to overload the new [] operator, which will generate the error given above.

Sample Code to Reproduce Behavior

   /* Compile options needed: none
   */

   #include <new.h>

   class example
   {
   public:

      void  *operator new [] ( size_t sz, const example& )
         { return( ::operator new [] ( sz )); }
   };

   void main(void)
   {
   }
