This class extends the QFile class with inter-process file locking capabilities. If an application requires that several processes should access the same file, QtLockedFile can be used to easily ensure that only one process at a time is writing to the file, and that no process is writing to it while others are reading it. \section1 Classes \list \i QtLockedFile\endlist \section1 Tested platforms \list \i Qt 4.4, 4.5 / Windows XP / MSVC.NET 2005 \i Qt 4.4, 4.5 / Linux / gcc \i Qt 4.4, 4.5 / MacOS X 10.5 / gcc \endlist */
