Compiler Error C2556

'function1': overloaded function differs only by return type from 'function2'

Remarks

The overloaded functions have different return types but the same parameter list. Each overloaded function must have a distinct formal parameter list.

Example

The following example generates C2556:

// C2556.cpp
// compile with: /c
int func();
double func();     // C2556
int func(int i);   // OK parameter lists differ
