if( -- m_cRefCount == 0 ) delete this;return m_cRefCount;

Though of course, if you take that fallthrough approach, you''d probably want to save m_cRefCount to a temporary variable; who knows whether it will still be valid after deletion...

Sneftel: No, suicide is never a solution

Having a private constructor? Ok, give me an example of this.

Ok, it might be useful but there must be better solutions and c++ is not really OO. But it''s like when I see a printf-statement in c++ code, I still go bezerk.

It is legal, but it is rarely a good thing to do.

sorry, i know this is an old thread but someone asked why one would ever use a private constructor. one good example of this is when implementing the singleton design pattern.
