FIX: Pointer to Member Function Is Not Shown as Reference

• Microsoft C/C++ Compiler (CL.EXE), used with:
  • Microsoft Visual C++ 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

While browsing for a member function of a C++ class, the browser 'References' list may not show the source line in which the address of the function is taken. See the sample code for an example.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.

MORE INFORMATION

The following sample code illustrates that the browser correctly shows all the references to a member variable, but it doesn't show the references to a member function where the address of the member function is taken.

Sample Code

   /* Compile options needed: /FR
   */ 

   class CTest
   {
   public:
      // Member function
      void MemFunc();
      // Member variable
      int m_i;
   };

   void CTest::MemFunc()
   {
   }

   // When you browse (Tools/Browse Menu) for the symbol 'MemFunc',
   // the 'References' list shows all the lines where 'MemFunc' is
   // referenced EXCEPT for the following source line.

   // Pointer to member function
   void (CTest::*pmfn)() = &CTest::MemFunc;

   // When you browse for the symbol 'm_i', the 'References' list
   // shows all the lines INCLUDING the following source line.

   // Pointer to member variable
   int CTest::*pmint = &CTest::m_i;

   void main()
   {
      CTest testObj;
      testObj.MemFunc();
      int j = testObj.m_i;
   }
