Apache Portable Runtime
From Wikipedia, the free encyclopedia
| Apache Portable Runtime | |
| Developer: | Apache Software Foundation |
|---|---|
| Latest release: | 1.2.8 / December 04, 2006 |
| OS: | Cross-platform |
| Use: | Development Library |
| License: | Apache 2.0 licence |

The Apache Portable Runtime (APR) is a supporting library for the Apache web server. It provides a set of APIs that map to the underlying operating system. Where the OS doesn't support a particular function, APR will provide a replacement. Thus, the APR can be used to make a program truly portable across platforms.
APR was originally a part of Apache, but has now been spun off into a separate project of the Apache Software Foundation, and is used by other applications to achieve platform independence.
The range of platform-independent functionality provided by APR includes:
- Memory allocation and memory pool functionality
- Atomicity operations
- Dynamic library handling
- File I/O
- Command argument parsing
- Locking
- Hash tables and arrays
- Mmap functionality
- Network sockets and protocols
- Thread, process and mutex functionality
- Shared memory functionality
- Time routines
- User and group ID services
- Glib provides similar functionality. It supports many more data structures and OS-independent functions, but fewer IPC-related functions (local and global locking, dynamic loading, or shared memory management are not provided).
- NSPR is a cross-platform abstraction library used by the Mozilla project. It is used by another subproject of Mozilla XPFE to provide cross-platform graphical user interface (GUI) functionality.
- Adaptive Communication Environment (ACE) is an object-oriented library similar in functionality to APR. It is widely deployed in commercial products[citation needed].
- WxWidgets is an object-oriented cross-platform GUI library that also provides abstraction classes for database communication, IPC and networking functionality.
