 | | • | | X/Open Portability Guide, Issue 3 (XPG3). X/Open is an international consortium of system vendors, ISVs, and users. Its purpose is to adopt existing standards and adapt them into a single, consistent Common Applications Environment (CAE). By awarding the X/Open brand trademark to products that comply with the CAE, X/Open hopes to ensure portability and connectivity of applications. The XPG3 includes IEEE Std 1003.1-1988, and has seven volumes covering system interface commands, utilities, system interfaces and headers, supplementary definitions, programming languages, data management, window management, and networking services. The current versions of Solaris 2.x, HP-UX 10.x, and IRIX 5.x also comply with XPG4, an updated version of the standard. | |
