Full Description

Scope

This standard defines a standard Ada language binding to ISO/lEC 9945-1: 1990 {2}, hereinafter referred to as "POSIX.1 [2]" to support application portability at the source code level. It is intended to be used by both application developers and system implementors.The focus of this standard the Ada interface to the is POSIX.1 {2} standard. The POSIX.1 {2} standard was initially defined using the C programming language. A language-independent definition of POSIX.1 {2} is under development, but at this time has not achieved a level of definition suitable as a starting point for this document.This standard is comprised of three major components:- Definitions for terminology and concepts, and definitions and specifications that govern program structures, language-system interaction, and related requirements- Definitions of the specific Ada interfaces to POSIX.1 {2} system services presented in the form. of Ada packages- Interpretations of Ada semantics with respect to POSIX.1 {2}

Abstract

New IEEE Standard - Inactive-Withdrawn.This standard is part of the POSIX series of standards for applications and user interfaces to open systems. It defines the Ada language bindings as package specifications and accompanying textual descriptions to the application program interface (API). This standard supports application portability at the source level through the binding between ISO 8652:1987 (Ada) and ISO/IEC 9945-1:1990 (IEEE Std 1003.1-1990) (POSIX). Terminology and general requirements, process primitives, the process environment, files and directories, input and output primitives, device- and class-specific functions, language-specific services for Ada, and system databases are covered. It also specifies behavior to support the binding that must be provided by the Ada compilation system. The emphasis in POSIX is on application programs, so the interfaces in this document are not sufficient to implement an Ada compilation system or a POSIX shell, nor is this standard meant to be sufficient for real-time applications.
