National bodies tha

26、t are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other interna

27、tional organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in

28、 the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at

29、 least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO/IEC 23360-6 was

30、 prepared by the Free Standards Group and was adopted, under the PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 22, Programming languages, their environments and system software interfaces. ISO/IEC 23360 consists of the following parts, under the g

31、eneral title Linux Standard Base (LSB) core specification 3.1: Part 1: Generic specification Part 2: Specification for IA32 architecture Part 3: Specification for IA64 architecture Part 4: Specification for AMD64 architecture Part 5: Specification for PPC32 architecture Part 6: Specification for PPC

32、64 architecture Part 7: Specification for S390 architecture Part 8: Specification for S390X architecture ISO/IEC 23360-6:2006(E) viii ISO/IEC 2006 All rights reservedIntroduction The specification carries a version number of either the form x.y or x.y.z. This version number carries the following mea

33、ning: The first number (x) is the major version number. All versions with the same major version number should share binary compatibility. Any addition or deletion of a new library results in a new version number. Interfaces marked as deprecated may be removed from the specification at a major versi

34、on change. The second number (y) is the minor version number. Individual interfaces may be added if all certified implementations already had that (previously undocumented) interface. Interfaces may be marked as deprecated at a minor version change. Other minor changes may be permitted at the discre

35、tion of the LSB workgroup. The third number (z), if present, is the editorial level. Only editorial changes should be included in such versions. Since this specification is a descriptive Application Binary Interface, and not a source level API specification, it is not possible to make a guarantee of

36、 100% backward compatibility between major releases. However, it is the intent that those parts of the binary interface that are visible in the source level API will remain backward compatible from version to version, except where a feature marked as in one release may be removed from a future relea

37、se. Implementors are strongly encouraged to make use of symbol versioning to permit simultaneous support of applications conforming to different releases of this specification. This is version 3.1 of the Linux Standard Base Core Specification. This specification is part of a family of specifications

38、 under the general title “Linux Standard Base (LSB) core specification 3.1“. Developers of applications orimplementations interested in using the LSB trademark should see the Free Standards Group Certification Policy for details. deprecatedThe LSB defines a binary interface for application programs

39、that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification includes information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface fo

40、r all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one. This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components ma

41、y be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they

42、use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in detail. Informati

43、on referenced in this way is as much a part of this document as is the information explicitly included here. I Introductory Elements 1 Scope 1.1 General The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. I

44、ts purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB. These specifications are composed of two basic parts: A common specification (“LSB-generic“ or “generic LSB“), ISO/IEC 23360-1, describing those parts of the interface that remain cons

45、tant across all implementations of the LSB, and an architecture-specific part (“LSB-arch“ or “archLSB“) describing the parts of the interface that vary by processor architecture. Together, the LSB-generic and the relevant architecture-specific part of ISO/IEC 23360 for a single hardware architecture

46、 provide a complete interface specification for compiled application programs on systems that share a common hardware architecture. ISO/IEC 23360-1, the LSB-generic document, is used in conjunction with an architecture-specific part. Whenever a section of the LSB-generic specification is supplemente

47、d by architecture-specific information, the LSB-generic document includes a reference to the architecture part. Architecture-specific parts of ISO/IEC 23360 may also contain additional information that is not referenced in the LSB-generic document. The LSB contains both a set of Application Program

48、Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation provides all of the ABIs listed here. The compilation system may replace

49、(e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed. The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification. 1.2 Module Specific Scope This is the PPC64 architecture-specific Core part of the Linux Standard Base (LSB). It supplements the gen
