IEEE 1003.1 Document Information:
Title
Standard for Information Technology - Portable Operating System Interface (POSIX)
The Institute of Electrical and Electronics Engineers, Inc.
Publication Date:
Jan 1, 2004
Scope:
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.
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.
The facilities provided in IEEE Std 1003.1-2001 are drawn from the
following base documents:
• IEEE Std 1003.1-1996 (POSIX-1) (incorporating IEEE Stds
1003.1-1990, 1003.1b-1993,
1003.1c-1995, and 1003.1i-1995)
• The following amendments to the POSIX.1-1990 standard:
- IEEE P1003.1a draft standard (Additional System Services)
- IEEE Std 1003.1d-1999 (Additional Realtime Extensions)
- IEEE Std 1003.1g-2000 (Protocol-Independent Interfaces (PII))
- IEEE Std 1003.1j-2000 (Advanced Realtime Extensions)
- IEEE Std 1003.1q-2000 (Tracing)
• IEEE Std 1003.2-1992 (POSIX-2) (includes IEEE Std 1003.2a-1992)
• The following amendments to the ISO POSIX-2: 1993 standard:
- IEEE P1003.2b draft standard (Additional Utilities)
- IEEE Std 1003.2d-1994 (Batch Environment)
• Open Group Technical Standard, February 1997, System Interface
Definitions, Issue 5 (XBD5)
(ISBN: 1-85912-186-1, C605)
• Open Group Technical Standard, February 1997, Commands and
Utilities, Issue 5 (XCU5)
(ISBN: 1-85912-191-8, C604)
• Open Group Technical Standard, February 1997, System Interfaces
and Headers, Issue 5
(XSH5) (in 2 Volumes) (ISBN: 1-85912-181-0, C606)
Note: XBD5, XCU5, and XSH5 are collectively referred to as the Base
Specifications.
• Open Group Technical Standard, January 2000, Networking
Services, Issue 5.2 (XNS5.2) (ISBN:
1-85912-241-8, C808)
• ISO/IEC 9899: 1999, Programming Languages - C.
IEEE Std 1003.1-2001 uses the Base Specifications as its
organizational basis and adds the
following additional functionality to them, drawn from the base
documents above:
• Normative text from the ISO POSIX-1: 1996 standard and the ISO
POSIX-2: 1993 standard not
included in the Base Specifications
• The amendments to the POSIX.1-1990 standard and the ISO
POSIX-2: 1993 standard listed above,
except for parts of IEEE Std 1003.1g-2000
• Portability Considerations
• Additional rationale and notes
The following features, marked legacy or obsolescent in the base
documents, are not carried forward
into IEEE Std 1003.1-2001. Other features from the base documents
marked legacy or obsolescent are
carried forward unless otherwise noted.
From XSH5, the following legacy interfaces, headers, and external
variables are not carried
forward:
advance(), brk(), chroot(), compile(), cuserid(), gamma(),
getdtablesize(), getpagesize(),
getpass(), getw(), putw(), re_comp(), re_exec(), regcmp(), regex(),
sbrk(), sigstack (), step(),
ttyslot(), valloc(), wait3(), 〈re_comp.h〉g,
〈regexp.h〉, 〈varargs.h〉,
loc1, __loc1, loc2, locs
From XCU5, the following legacy utilities are not carried forward:
calendar, cancel, cc, col, cpio, cu, dircmp, dis, egrep, fgrep, line,
lint, lpstat, mail, pack,
pcat, pg, spell, sum, tar, unpack, uulog, uuname, uupick, uuto
In addition, legacy features within non-legacy reference pages (for
example, headers) are not
carried forward.
From the ISO POSIX-1: 1996 standard, the following obsolescent
features are not carried forward:
Page 112, CLK_TCK
Page 197 tcgetattr() rate returned option
From the ISO POSIX-2: 1993 standard, obsolescent features within the
following pages are not
carried forward:
Page 75, zero-length prefix within PATH
Page 156, 159 set
Page 178, awk, use of no argument and no parentheses with length
Page 259, ed
Page 272, env
Page 282, find -perm[-]onum
Page 295-296, egrep
Page 299-300, head
Page 305-306, join
Page 309-310, kill
Page 431-433, 435-436, sort
Page 444-445, tail
Page 453, 455-456, touch
Page 464-465, tty
Page 472, uniq
Page 515-516, ex
Page 542-543, expand
Page 563-565, more
Page 574-576, newgrp
Page 578, nice
Page 594-596, renice
Page 597-598, split
Page 600-601, strings
Page 624-625, vi
Page 693, lex
The c89 utility (which specified a compiler for the C Language
specified by the ISO/IEC 9899: 1990
standard) has been replaced by a c99 utility (which specifies a
compiler for the C Language
specified by the ISO/IEC 9899: 1999 standard).
From XSH5, text marked OH (Optional Header) has been reviewed on a
case-by-case basis and removed
where appropriate. The XCU5 text marked OF (Output Format Incompletely
Specified) and UN (Possibly
Unsupportable Feature) has been reviewed on a case-by-case basis and
removed where appropriate.
For the networking interfaces, the base document is the XNS, Issue 5.2
specification. The following
parts of the XNS, Issue 5.2 specification are out of scope and not
included in IEEE Std
1003.1-2001:
• Part 3 (XTI)
• Part 4 (Appendixes)
Since there is much duplication between the XNS, Issue 5.2
specification and IEEE Std 1003.1g-2000,
material only from the following sections of IEEE Std 1003.1g-2000 has
been included:
• General terms related to sockets (Section 2.2.2)
• Socket concepts (Sections 5.1 through 5.3, inclusive)
• The pselect() function (Sections 6.2.2.1 and 6.2.3)
• The sockatmark () function (Section 5.4.13)
• The 〈sys/select.h〉 header (Section 6.2)
Emphasis is placed on standardizing existing practice for existing
users, with changes and
additions limited to correcting deficiencies in the following areas:
• Issues raised by IEEE or ISO/IEC Interpretations against IEEE
Std 1003.1 and IEEE Std 1003.2
• Issues raised in corrigenda for the Base Specifications and
working group resolutions from
The Open Group
• Corrigenda and resolutions passed by The Open Group for the
XNS, Issue 5.2 specification
• Changes to make the text self-consistent with the additional
material merged
• A reorganization of the options in order to facilitate
profiling, both for smaller profiles
such as IEEE Std 1003.13, and larger profiles such as the Single UNIX
Specification
• Alignment with the ISO/IEC 9899: 1999 standard
