A search on the IEEE site says 1003.5c-1998 has been WITHDRAWN (no longer maintained, may have obsolete and erroneous information). IEEE> Description: This standard is part of the POSIX ®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 unctions,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 inter-faces,event management,network support functions,and protocol-specific mappings are covered It also specifies behavior to support the binding that must be proviced by the Ada. I suppose the "...behavior to support the binding..." might cover the semantics question... or just defer something to the closest OS provided equivalent. I could not find any link in the search to a NEWER 1003.5'x'. 1003.5-1998 (no subpart letter, "Binding for System API") is listed as SUPERSEDED. But can't find a reference to what replaced it... Looks like almost all the POSIX stuff is "superseded" 1003.1-1990 abstract says "see ISO/IEC 9945-1" Ah, something active... 1003.1-2008 IEEE> Description: POSIX.1-2008 is simultaneously IEEE Std 1003.1 -2008 and The Open Group Technical Standard Base Specifications, Issue 7. POSIX. 1-2008 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. POSIX. 1-2008 is intended to be used by both application developers and system implementors and comprises four major components (each in an associated volume): [1]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. [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. [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. [4] Extended rationale that did not fit well into the rest of the document structure, which contains historical information concerning the contents of POSIX. 1-2008 and why features were included or discarded by the standard developers, is included in the Rationale (Informative) volume. The following areas are outside the scope of POSIX. 1-2008: Graphics interfaces Database management system interfaces Record I/O considerations Object or binary code portability System configuration and resource availability. POSIX. 1-2008 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. Note that most of those predate Ada-95, much less the 2005/2012 updates. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
