V556. Values of different enum types are compared.
The analyzer detected a potential error: code contains comparison of enum values which have different types.
Consider a sample:
enum ErrorTypeA { E_OK, E_FAIL };
enum ErrorTypeB { E_ERROR, E_SUCCESS };
void Foo(ErrorTypeB status) {
if (status == E_OK)
{ ... }
}The programmer used a wrong name in the comparison by accident, so the program's logic is disrupted. This is the correct code:
void Foo(ErrorTypeB status) {
if (status == E_SUCCESS)
{ ... }
}Comparison of values of different enum types is not necessarily an error, but you must review such code.
