What is wrong with using inline functions?

Question

While it would be very convenient to use inline functions at some situations,

Are there any drawbacks with inline functions?

Conclusion:

Answer 1

I agree with the other posts:

• inline may be superfluous because the compiler will do it
• inline may bloat your code

A third point is it may force you to expose implementation details in your headers, .e.g.,

class OtherObject;

class Object {
public:
    void someFunc(OtherObject& otherObj) {
        otherObj.doIt(); // Yikes requires OtherObj declaration!
    }
};

Without the inline a forward declaration of OtherObject was all you needed. With the inline your header needs the definition for OtherObject.
