Question

I'm fixing some PC Lint Plus Warnings and errors. The codebase has IDL files for COM structs. Hence the auto generated h files have virtual functions for COM class but no virtual destructor. Following is the snippet from auto-generated header from IDL file.

C++

MIDL_INTERFACE("9BY99957-418C-4A53-9C86-DD9834B55882")
ISomeInterface : public IUnknown
{
public:
virtual HRESULT foo() = 0;
}

When running Pc Lint Plus, i get this warning

Quote:
warning 3412:'struct ISomeInterface' has virtual functions but non-virtual destructor

What I have tried:

I'm thinking of suppressing these warnings since there is not much i could do here. But has anyone faced this issue and did anyone found a way to overcome it ?
