Locked File

Description The QtLockedFile class extends QFile with advisory locking functions.

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.

This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit http://www.trolltech.com/products/solutions/catalog/4/.
