This standard is simultaneously ISO/IEC 9945, IEEE Std 1003.1, and forms the core of the Single Unix Specification, Version 3. This 2004 edition includes IEEE Std 1003.1-2001/Cor 1-2002 and IEEE Std 1003.1-2001/Cor 2-2004 incorporated into IEEE Std 1003.1-2001 (the base document). The two Corrigenda address problems discovered since the approval of IEEE Std 1003.1-2001. These changes are mainly due to resolving integration issues raised by the merger of the base documents that were incorporated into the IEEE Std 1003.1-2001, which is the single common revision to IEEE Std 1003.1-1996, IEEE Std 1003.2-1992, ISO/IEC 9945-1:1996, ISO/IEC 9945-2:1993, and the Base Specifications of The Open Group Single UNIX® Specification, Version 2.

P1003.1
IEEE Draft Standard for Information Technology--Portable Operating System Interface (POSIX(TM)) Base Specifications, Issue 8
POSIX.1-202x defines a standard operating system interface and environment, including a command interpreter (or u201cshellu201d), and common utility programs to support applications portability at the source code level. POSIX.1-202x is intended to be used by both application developers and system implementors and comprises four major components (each in an associated volume):nu2022 General terms, concepts, and interfaces common to all volumes of this standard, including utility conventions and C-language header definitions, are included in the Base Definitions volume.nu2022 Definitions for system service functions and subroutines, language-specific system services for the C programming language, function issues, including portability, error handling, and error recovery, are included in the System Interfaces volume.nu2022 Definitions for a standard source code-level interface to command interpretation services (a u201cshellu201d) and common utility programs for application programs are included in the Shell and Utilities volume.nu2022 Extended rationale that did not fit well into the rest of the document structure, which contains historical information concerning the contents of POSIX.1-202x and why features were included or discarded by the standard developers, is included in the Rationale (Informative) volume.nThe following areas are outside the scope of POSIX.1-202x:nu2022 Graphics interfacesnu2022 Database management system interfacesnu2022 Record I/O considerationsnu2022 Object or binary code portability nu2022 System configuration and resource availability POSIX.1-202x describes the external characteristics and facilities that are of importance to application developers, rather than the internal construction techniques employed to achieve these capabilities. Special emphasis is placed on those functions and facilities that are needed in a wide variety of commercial applications.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
