libjio Description

An open source and free library for Journaled I/O libjio is a free userspace library to do journaled, transaction-oriented I/O.libjio provides a very simple API to commit and rollback transactions, and on top of that a UNIX-alike set of functions to perform most regular operations (open(), read(), write(), etc.) in a non-intrusive threadsafe and atomic way, with safe and fast crash recovery.The libjio library guarantees file integrity even after unexpected crashes, never leaving your files in an inconsistent state.On the disk, the file you work on is exactly like a regular one, but a special directory is created to store in-flight transactions.libjio is developed using in plain C, in less than 1500 lines of code, and has no dependencies on external libraries.libjio is based on the traditional POSIX API and follows the Single UNIX Specification, so it should be portable to all major UNIX variants without problems.
