qAtomicAssign()

template<typename T >

QT_WARNING_POP void qAtomicAssign ( T *& d, T * x )

inline

This is a helper for the assignment operators of implicitly shared classes.

Your assignment operator should look like this:

qAtomicDetach()

template<typename T >

void qAtomicDetach ( T *& d )

inline

This is a helper for the detach method of implicitly shared classes.

Your private class needs a copy constructor which copies the members and sets the refcount to 1. After that, your detach function should look like this:

Definition at line 199 of file qatomic.h.
