thread safe classes

[gsherp]

How does one go about making a class that is thread safe?

Say we created the simple animal class

class animal
{            public:
            virtual void eat() const { cout << " I eat like an animal. " << endl; }
            virtual ~animal() { }
}

how do i go about to ensure that this class is thread safe.

I am new to the multi-threading subject.

Thanks.

If you are not having any static members in the class and if u are not using any global variables in side the member function then you can say the class method is thread safe.

But there may be other factors too.

put the cout << ... << endl; statement within critical section , as the streams are not guaranteed to be thread-safe.
