All rights reserved. Base Specifications, Issue 7 Abstract POSIX.1-2008 is simultaneously IEEE Std 1003.1-2008

4、and The Open Group Technical Standard Base Specifications, Issue 7. This 2013 Edition includes IEEE Std 1003.1-2008/Cor 1-2013 incorporated into IEEE Std 1003.1-2008 (the base document). The Technical Corrigendum addresses problems discovered since the approval of IEEE Std 1003.1-2008. POSIX.1-2008

5、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 compri

6、ses four major components (each in an associated volume): 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. Definitions for system service functions and subrout

7、ines, 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. Definitions for a standard source code-level interface to command interpretation services (a “shell”) and

8、common utility programs for application programs are included in the Shell and Utilities volume. 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

9、 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 availabil

10、ity 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 var
