It must be called through the 00033 public "MultiplyNumbers" function which is available in the extension dll. 00034 */ 00035 00036 00037 00038 00039 #include <NumberStore.h> 00040 00041 00042 00043 //This constant is defined in the CPP to demonstrate an intrusive change; 00044 //DoMultiplyNumbers must be implemented in this DLL in order to see this const 00045 const TInt KMagicMultiplyer=2; 00046 00047 //Function implementations of all _original_ functions 00048 00049 EXPORT_C CNumberStore::CNumberStore () 00050 { 00051 } 00052 00053 EXPORT_C CNumberStore::CNumberStore (TInt aNumber1, TInt aNumber2) 00054 { 00055 SetNumber1(aNumber1); 00056 SetNumber2(aNumber2); 00057 } 00058 00059 EXPORT_C void CNumberStore::SetNumber1 (TInt aNumber1) 00060 { 00061 iNumber1=aNumber1; 00062 } 00063 00064 EXPORT_C void CNumberStore::SetNumber2 (TInt aNumber2) 00065 { 00066 iNumber2=aNumber2; 00067 } 00068 00069 EXPORT_C TInt CNumberStore::Number1 () const 00070 { 00071 return iNumber1; 00072 } 00073 00074 EXPORT_C TInt CNumberStore::Number2 () const 00075 { 00076 return iNumber2; 00077 } 00078 00083 EXPORT_C TInt CNumberStore::DoMultiplyNumbers() const 00084 { 00085 return (iNumber1*iNumber2*KMagicMultiplyer); 00086 }
