Comparison of IEEE Portable Operating System Interface (POSIX). Part 1 and X/Open Single Unix Specifications (SUS).

Abstract

This document is a textual comparison study of the IEEE 1003.1 Portable Operating System Interface (POSIX) - Part 1: System Application Program Interface (C Language) (IEEE 1003.1:1990) and X/OPEN Single UNIX Specification (SUS). The purpose of this document is to aid in determining the criteria needed for the successor to FIPS PUB 151-2. It can also be used as a tool to ascertain the differences between the two specifications. However, note that this document does not attempt to address application portability concerns between the two specifications. To determine the application portability of some commands between an XPG4 UNIX-Branded implementation and a PIPS 151-2 certified implementation, further study is required.
