About This Item
ISO/IEC/IEEE 9945:2009/COR1:2013 provides a technical corrigendum to the Information technology - Portable Operating System Interface (POSIX®) Base Specifications, Issue 7 - Technical Corrigendum 1, helping users apply the base specification with the intended corrections and clarifications. For engineering, compliance, and procurement teams, ISO/IEC/IEEE 9945:2009/COR1:2013 is relevant when operational consistency, documented evaluation, and technical review depend on the corrected wording of the parent POSIX reference. It supports careful interpretation in standards-based workflows where accuracy matters.
What is ISO/IEC/IEEE 9945:2009/COR1:2013?
This document is a corrigendum connected to ISO/IEC/IEEE 9945, rather than a standalone base specification. It is intended to correct or refine the published text of Information technology - Portable Operating System Interface (POSIX®) Base Specifications, Issue 7 - Technical Corrigendum 1, which is often used as a compliance reference for portable operating system behavior and software interface expectations. In technical documentation, it may be consulted during verification activities, conformity assessment, and internal review of implementation details.
Applications of ISO/IEC/IEEE 9945:2009/COR1:2013
ISO/IEC/IEEE 9945:2009/COR1:2013 is typically used when teams need to validate or interpret POSIX-related requirements in software platforms, operating environments, and system integration work. It can support procurement review for products that claim POSIX alignment, as well as laboratory evaluation and technical validation where documented behavior must be checked against the corrected base text. It is also useful in engineering documentation, quality workflows, and compliance workflows that require a precise reference for system portability and interface consistency.
Why is ISO/IEC/IEEE 9945:2009/COR1:2013 important?
For organizations working with portable operating system interfaces, the corrigendum helps reduce ambiguity and improves confidence in technical assessment. It can support testing consistency, risk management, and compliance preparation by aligning teams to the corrected language of the parent document. In practice, that matters when software behavior, interoperability, and implementation claims must be reviewed carefully for procurement, certification-related analysis, or internal quality assurance. Using the corrigendum alongside the base specification helps maintain a more reliable compliance reference.
