This standard is part of the POSIX(R) series of standards or applications and user inter-faces to open systems. It defines the Ada language bindings as package specifications and accompanying textual descriptions of the application program interface (API). This standard supports application portability at the source code level through the binding between ISO 8652:1995 (Ada) and ISO/IEC 9945-1:1996 (IEEE Std 1003.1-1996)(POSIX) as amended by IEEE P1003.1g/D6.6. Terminology and general requirements, process primitives, the process environment, files and directories, input and output primaries, device-and class-specific functions, language-specific services or Ada, system databases, synchronization, memory management, execution scheduling, clocks and timers, message passing, task management, the XTI and socket detailed network interfaces, event management, network support functions, and protocol-specific mappings are covered It also specifies behavior to support the binding that must be provided by the Ada.

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 of the application program interface (API). This standard supports application portability at the source code level through the binding between ISO 8652: 1987 (Ada) and ISO/IEC 9945-1: 1990 (IEEE Std 1003.1-1990) (POSIX), as amended by IEEE Std 1003.1b-1993, IEEE Std 1003.1c-1995, and IEEE Std 1003.1I-1995. 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, system databases, synchronization, memory management, execution scheduling, clocks and timers, and message passing are covered. It also specifies behavior to support the binding that must be provided by the Ada compilation system.

This standard defines the requirements and guidelines for test method specifications and test method implementations for measuring conformance to POSIX standards. Test specification standard developers for other Application Programming Interface (API) standards are encouraged to use this standard. This document is aimed primarily at developers and users of test method specifications and implementations.

IEEE Std 2003.1-1992 provides a definition of the requirements placed upon providers of POSIX test methods for POSIX.1 (IEEE Std 10031-1990; ISO/IEC 9945-1: 1990). These requirements consist of a POSIX.1-ordered list of assertions defining those aspects of POSIX.1. that are to be tested and the associated test methods that are to be used in performing those tests. This standard is aimed primarily at POSIX.1 test suite providers and POSIX.1 implementors. This standard specifies those aspects of POSIX.1 that shall be verified by conformance test methods.

This standard defines the test method specifications for IEEE Std 1003.1b-1993 (based on the document corresponding to the merger of IEEE Std 1003.1-1990 and IEEE Std 1003.1b-1993). The test method specifications consist of assertions to be tested and related test procedures. As an amendment to IEEE Std 1003.1-1990, this standard is structured to amend those portions of IEEE Std 2003.1-1992 {4} (the test method specification for IEEE Std 1003.1-1990) that correspond to the amended parts of IEEE Std 1003.1-1990. This standard is aimed primarily at providers of test methods for IEEE Std 1003.1b-1993 and at implementors of IEEE Std 1003.1b-1993.

A definition of the requirements placed upon providers of a POSIX Conformance Test Suite for the POSIX.2 standard (ISO/IEC9945-2:1993,IEEE/ANSI Std. 1003.2-1992) is provided. These requirements consist of a list of assertions defining those aspects of POSIX.2 that are to be tested and the associated test methods that are to be used in performing those tests. This standard is primarily aimed at test suite providers but it also defines to POSIX.2 implementors those aspects of the standard that will be verified by a conformance test suite.
