-/**
- * \class QxtFileLock QxtFileLock
- * \ingroup QxtCore
- * \brief The QxtFileLock class provides a crossplattform way to lock a QFile.
- *
- * It supports the range locking of a file. The File will take parentship of the lock.<br>
- * The lock gets cleaned up with the QFile, and it is released when the QFile is closed.<br>
- *
- * Example usage:
- * \code
- * off_t lockstart = 0x10;
- * off_t locklength = 30
- *
- * QFile file("test.lock");
- *
- * //the lock gets deleted when file is cleaned up
- * QxtFileLock * writeLock = new QxtFileLock(&file,lockstart,locklength,QxtFileLock::WriteLock);
- * if(file.open(QIODevice::ReadWrite))
- * {
- *     if(writeLock->lock())
- *     {
- *          // some write operations
- *         writeLock->unlock();
- *     }
- *      else
- *          //lock failed
- * }
- * \endcode
- * \note QxtFileLock behaves different than normal unix locks on *nix. A thread can writelock the region of a file only ONCE if it uses two  different handles.
- *           A different thread can not writelock a region that is owned by a other thread even if it is the SAME process.
- * \note On *nix this class uses fctnl to lock the file. This may not be compatible to other locking functions like flock and lockf
- * \note Please do not mix QxtFileLock and native file lock calls on the same QFile. The behaviour is undefined
- * \note QxtFileLock lives in the same thread as the passed QFile
- * \warning due to a refactoring issues of QFile this class will not work with Qt from 4.3 on. This will be fixed in 4.3.2
- * \warning not part of 0.2.4
