标准简介：IEEE Std 1003.1-2001 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 applications developers
and system implementors.
IEEE Std 1003.1-2001 comprises four major components (each in an associated volume):
1. General terms, concepts, and interfaces common to all volumes of IEEE Std 1003.1-2001,
including utility conventions and C-language header definitions, are included in the Base
Definitions volume of IEEE Std 1003.1-2001.
11 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
IEEE Std 1003.1-2001.
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 IEEE Std 1003.1-2001.
4. Extended rationale that did not fit well into the rest of the document structure, containing
historical information concerning the contents of IEEE Std 1003.1-2001 and why features
were included or discarded by the standard developers, is included in the Rationale
(Informative) volume of IEEE Std 1003.1-2001.
The following areas are outside of the scope of IEEE Std 1003.1-2001:
• Graphics interfaces
• Database management system interfaces
• Record I/O considerations
• Object or binary code portability
• System configuration and resource availability
IEEE Std 1003.1-2001 describes the external characteristics and facilities that are of importance to
applications 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.
