Apache Portable Runtime 1.2.2 Released
The Apache Software Foundation and the Apache Portable Runtime
Project are proud to announce the General Availability of
version 1.2.2 of the Apache Portable Runtime, APR.
APR is available for download from:
http://apr.apache.org/download.cgi
This version of APR is principally a bug fix release.
The mission of the Apache Portable Runtime Project is to create
and maintain software libraries that provide a predictable and
consistent interface to underlying platform-specific
implementations. The primary goal is to provide an API to
which software developers may code and be assured of predictable
if not identical behavior regardless of the platform on which
their software is built, relieving them of the need to code
special-case conditions to work around or take advantage of
platform-specific deficiencies or features.
APR and its companion libraries are implemented entirely in C
and provide a common programming interface across a wide variety
of operating system platforms without sacrificing performance.
Currently supported platforms include:
* UNIX
* Windows
* Netware
* Mac OS X
* OS/2
* BeOS
To give a brief overview, the primary core subsystems of APR 1.2
include the following:
* Atomic operations
* Dynamic Shared Object loading
* File I/O
* Locks (mutexes, condition variables, etc)
* Memory management (high performance allocators)
* Memory-mapped files
* Multicast Sockets
* Network I/O
* Shared memory
* Thread and Process management
* Various data structures (tables, hashes, priority queues, etc)

Users of APR 0.9 should be aware that migrating to the APR 1.x
programming interfaces may require some adjustments; APR 1.x is
not binary compatible with earlier APR 0.9 releases. Users of
APR 1.x can expect consistent interfaces and binary compatibility
through the entire APR 1.x release cycle, as defined in our
versioning rules:
http://apr.apache.org/versioning.html
APR is already used extensively by the Apache HTTP Server
version 2.0 and the Subversion revision control system, to
name but a few. We list all known projects using APR at
http://apr.apache.org/projects.html -- so please let us know
if you find our libraries useful in your own projects!
