Draft Standard for Information Technology-Portable Operating System Interface (POSIX)

pending
Organization: IEEE
Publication Date: 1 December 2023
Status: pending
Page Count: 4,101
scope:

POSIX.1-202x defines a standard operating system interface and environment, including a command interpreter (or ``shell''), and common utility programs to support applications portability at the source code level. It is intended to be used by both application developers and system implementors.

POSIX.1-202x comprises four major components (each in an associated volume):

1. General terms, concepts, and interfaces common to all volumes of POSIX.1-202x, including utility conventions and C-language header definitions, are included in the Base Definitions volume of POSIX.1-202x.

2. 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 of POSIX.1-202x.

3. Definitions for a standard source code-level interface to command interpretation services (a ``shell'') and common utility programs for application programs are included in the Shell and Utilities volume of POSIX.1-202x.

4. Extended rationale that did not fit well into the rest of the document structure, containing 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 of POSIX.1-202x.

The following areas are outside of the scope of POSIX.1-202x:

• Graphics interfaces

• Database management system interfaces

• Record I/O considerations

• Object or binary code portability

• 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.

The facilities provided in POSIX.1-202x are drawn from the following base documents:

• IEEE Std 1003.1-2017 (POSIX.1-2017)

• IEEE Std 1003.26-2003 (POSIX.26-2003)

• ISO/IEC 9899: 2018, Programming Languages - C (C17)

• ISO/IEC TR 24731-2: 2010, Programming languages, their environments and system + software interfaces - Extensions to the C library - Part 2: Dynamic Allocation Functions +

• The Open Group Standard, 2021, Additional APIs for the Base Specifications Issue 8, Part 1 +

• The Open Group Standard, 2022, Additional APIs for the Base Specifications Issue 8, Part 2

Emphasis has been placed on standardizing existing practice for existing users, with changes and additions limited to correcting deficiencies in the following areas:

• Issues raised by Austin Group defect reports and IEEE Interpretations against IEEE Std | 1003.1.

• Issues raised in corrigenda for The Open Group Standards and working group resolutions from The Open Grou

• Changes to make the text self-consistent with the additional material merged

• Features, marked obsolescent in the base documents, have been considered for removal in this version

• Alignment with the ISO/IEC 9899: 2018 standard
