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 (OS). Where the OS does not support a particular function, APR will provide an emulation. Thus programmers can use the APR to make a program truly portable across platforms. APR originally formed a part of Apache HTTP Server, but the Apache Software Foundation spun it off into a separate project. Other applications can use it to achieve platform independence. == Functionality == The range of platform-independent functionality provided by APR includes: * Memory allocation and memory pool functionality * Atomic 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 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apache Portable Runtime」の詳細全文を読む スポンサード リンク
