1003.1-2008/Cor 1-2013 is the technical corrigendum for the Portable Operating System Interface (POSIX(TM)) Base Specifications, Issue 7, addressing corrections and clarifications to the IEEE 1003.1-2008 framework. In practice, it supports more accurate implementation of operating system interfaces and helps reduce ambiguity in compliance and testing. For software and systems teams working with portable UNIX-like environments, this document is a useful reference for maintaining consistency across platforms and releases.

1003.1-2008/Cor 1-2013 overview

This standard update sits within the IEEE POSIX base specification family and is intended to refine the original requirements rather than redefine them. The corrections help align interpretation of the interface rules used by applications, utilities, and system services that depend on POSIX behavior. As a result, 1003.1-2008/Cor 1-2013 is relevant when evaluating conformance, resolving specification errors, or comparing implementation details across software environments.

Typical use cases

This corrigendum is commonly used when reviewing operating system compliance for portable applications, embedded platforms, and enterprise systems that depend on POSIX interfaces. It may also support engineering teams that maintain build environments, system libraries, or test suites tied to IEEE 1003.1-2008. In procurement or internal governance, it can help clarify which corrected requirements should guide specification checks, acceptance testing, and interoperability planning.

Why this standard matters

Keeping technical references aligned with 1003.1-2008/Cor 1-2013 helps improve consistency in implementation and reduces the risk of relying on outdated wording. For organizations that manage portable software or cross-platform systems, the corrigendum supports clearer compliance decisions and more reliable verification. It is especially useful where small specification differences can affect system behavior, compatibility, or the interpretation of interface requirements during design and testing.
