Do not time out for -1 msec (wait methods)
According to the documentation of QIODevice: * http://qt-project.org/doc/qt-5.1/qtcore/qiodevice.html#waitForBytesWritten * http://qt-project.org/doc/qt-5.1/qtcore/qiodevice.html#waitForReadyRead these wait methods should not time out if msecs is -1. Currently, the behavior does not match the expected behavior as the negative values were overridden by zero. The operation returns as soon as the event loop processing happens. Now this problem is solved for Windows: the INFINITE flag has been added to the WaitForMultipleObjects call. See the MSDN documentation for details below: http://msdn.microsoft.com/en-us/library/windows/desktop/ms687025%28v=vs.85%29.aspx Note: the check is added only for -1 to be consistent with the behavior of other QIODevice subclasses. If it is any other negative integer, the value will be cast to the corresponding positive value which will indicate the waiting time. Tested with Qt4 and then Qt5.
