POSIX.1-2024 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.1-2024 comprises four major components (each in an associated volume): 1. General terms, concepts, and interfaces common to all volumes of POSIX.1-2024, including utility conventions and C-language… read more header definitions, are included in the Base Definitions volume of POSIX.1-2024. 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.1-2024. 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.1-2024. 4. Extended rationale that did not fit well into the rest of the document structure, containing historical information concerning the contents of POSIX.1-2024 and why features were included or discarded by the standard developers, is included in the Rationale (Informative) volume of POSIX.1-2024. The following areas are outside of the scope of POSIX.1-2024: --Graphics interfaces --Database management system interfaces --Record I/O considerations --Object or binary code portability --System configuration and resource availability POSIX.1-2024 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.

This standard is applicable to the development and use of conformance testing methodologies for POSE standards. The generic test methods identified in this standard shall be used in conjunction with test methods identified for a specific standard. This standard is intended for use by working groups developing test methods for POSM standards, developers of POSM test methods, and users of POSIX test methods. The purpose of this standard is to define general rules for developing test assertions… read more and related test methods for measuring conformance of an implementation to POSE standards. Test methods may include POSM Conformance Test Suites (PCTS), POSE Conformance Test Procedures (PCTP), and audita of POSM Conformance Documents (PCD). Testing conformance of an implementation to a standard includes testing the claimed capabilities and behavior of the implementation with respect to the conformance requirements of the standard. Test methods are intended to provide a reasonable, practical assurance that the implementation conforms to the standard. Use of these test methods will not guarantee conformance of an implementation to the standard; that normally would require exhaustive testing (see 4.2.11, which is impractical for both technical and economic reasons. read less

This standard defines extensions to POSIX.1 {2} to support application portability at the source-code level. It is intended to be used by both application developers and system implementers. The scope of this standard is to define a portable application interface for applications with realtime constraints requiring the ability to control special devices from the application itself. The intent is to take existing realtime operating system practice and add it to the POSIX family of standards.… read more Specifically within the scope is to define interfaces which do not preclude high-performance implementations on traditional uniprocessor realtime systems, as well as on multiprocessors. Wherever possible, the requirements of other application environments were included in the interface definition. read less
