4、08 is simultaneously IEEE Std 1003.1-2008 and The Open Group Standard Base Specifications, Issue 7. This 2016 Edition includes IEEE Std 1003.1-2008/Cor 1-2013 and IEEE Std 1003.1-2008/Cor 2-2016 incorporated into IEEE Std 1003.1-2008 (the base document). The Technical Corrigenda address problems dis

5、covered since the approval of IEEE Std 1003.1-2008. 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

6、by both application developers and system implementors and comprises four major components (each in an associated volume): x 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 Defin

7、itions volume. x 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. x Definitions for a standard source c

8、ode-level interface to command interpretation services (a “shell”) and common utility programs for application programs are included in the Shell and Utilities volume. x Extended rationale that did not fit well into the rest of the document structure, which contains historical information concerning

9、 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: x Graphics interfaces x Database management system interfaces x Record I/O consideration

10、s x Object or binary code portability x 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

11、 emphasis is placed on those functions and facilities that are needed in a wide variety of commercial applications.

The existence of an IEEE standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE standard. Furthermore, the viewpoint expressed at the ti

In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for, or on behal

Any person utilizing any IEEE Standards document should rely upon his or her own independent judgment in the exercise of reasonable care in any given circumstances or, as appropriate

19、, seek the advice of a competent professional in determining the appropriateness of a given IEEE standard. IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES;

23、al position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be conside

24、red the personal views of that individual rather than the formal position of IEEE. Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or a

25、dvice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and

26、questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. Fo

27、r the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group. Comments on standards should be submitted to the following address: Secretary, IEEE-SA Standards Board 44

28、5 Hoes Lane Piscataway, NJ 08854 USA Laws and regulations Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the provisions of any IEEE Standards document does not imply compliance to any applicable regulatory requirements. Implementers of the stand

29、ard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so. Copyrights IEEE draft and approved

30、 standards are copyrighted by IEEE under U.S. and international copyright laws. They are made available by IEEE and are adopted for a wide variety of both public and private uses. These include both use, by reference, in laws and regulations, and use in private self-regulation, standardization, and

31、the promotion of engineering practices and methods. By making these documents available for use and adoption by public authorities and private users, IEEE does not waive any rights in copyright to the documents. Photocopies Subject to payment of the appropriate fee, IEEE will grant users a limited,

32、non-exclusive license to photocopy portions of any individual standard for company or organizational internal use or individual, non-commercial use only. To arrange for payment of licensing fees, please contact Copyright Clearance Center, Customer Service, 222 Rosewood Drive, Danvers, MA 01923 USA;

34、sers of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current ed

35、ition of the document together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although

36、 still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard. In order to determine whether a given document is the current edition and whether it has been amended through the issuance of am

37、endments, corrigenda, or errata, visit the IEEE-SA Website at http:/standards.ieee.org or contact IEEE at the address listed previously. For more information about the IEEE SA or IEEEs standards development process, visit the IEEE-SA Website at http:/standards.ieee.orgdevelopindex.html. Errata Errat

38、a, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http:/standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errata periodically. Patents Attention is called to the possibility that implementation of this standard may

39、require use of subject matter covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted

40、Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, w

41、ith reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants desiring to obtain such licenses. Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not responsible for identifying Essential Patent Claims for

42、 which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discri

43、minatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
