QBasicAtomicPointer usage example

[papu12]

Is there any example code of QBasicAtomicPointer usage --- Thanks in advance

Hi,

AFAIK QBasicAtomicPointer is an internal class and should not be used.

If you need something like that you should use QAtomicPointer

Thanks .I made changes as suggested by you:
@
#if QT_VERSION < QT_VERSION_CHECK(4, 4, 0)
#define LOG4QT_DECLARE_STATIC_LOGGER(FUNCTION, CLASS)
static Log4Qt::Logger *FUNCTION()
{
static Log4Qt::Logger *p_logger = 0;
if (!p_logger)
{
q_atomic_test_and_set_ptr(
&p_logger,
0,
Log4Qt::Logger::logger( #CLASS ));
}
return p_logger;
}
#else
#define LOG4QT_DECLARE_STATIC_LOGGER(FUNCTION, CLASS) \

#define LOG4QT_DECLARE_STATIC_LOGGER(FUNCTION, CLASS)                     \
    static Log4Qt::Logger *FUNCTION()                                     \
    {                                                                     \
        static QAtomicPointer<Log4Qt::Logger> p_logger ;            \
   //         Q_ATOMIC_INITIALIZER(0);                                 \
                                                                           \
        if (!p_logger.testAndSetOrdered(0,                                 \
                Log4Qt::Logger::logger( #CLASS )))                        \
        {                                                                 \
            p_logger.testAndSetOrdered(0,                                 \
            Log4Qt::Logger::logger( #CLASS ));                            \
        }                                                                 \
        return p_logger;                                                  \
}

#endif

seems this error is removed , others error pops up , looking at them.
Thanks much.

You should first check if the current version of Log4Qt has been validated against Qt 5

[papu12]

nope, its not , but we used it , so we plan to update it to make compatible with qt5

[papu12]

also , using QAtomicPointer is not solving , still has type casting issue. Struggling with that.

Does
@
return (Log4Qt::Logger*) p_logger;
@

work?
