s/qvector/int/ and that answers your question. If you're mutating the same variable, then either use a mutex or use atomic operations (for which there aren't any for QVector). If you're operating on different variables, then you're safe, regardless of where the actual data came from. If you're only reading the same variable and the proper memory barriers were in place for obtaining it, then you can do that without a mutex or atomic operations. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
