41、e Extension C Language).This standard defines the test method specifications for IEEE Std 1003.1b-1993 (based on thedocument corresponding to the merger of IEEE Std 1003.1-1990 and IEEE Std 1003.1b-1993).The test method specifications consist of assertions to be tested and related test procedures. A
42、san amendment to IEEE Std 1003.1-1990, this standard is structured to amend those portions ofIEEE Std. 2003.1-1992 4 (the test method specification for IEEE Std 1003.1-1990) thatcorrespond to the amended parts of IEEE Std 1003.1-1990. This standard is aimed primarily atproviders of test methods for
43、IEEE Std 1003.1b-1993 and at implementors of IEEE Std 1003.1b-1993.Organization of This StandardThis document is organized into five parts, as follows:(1) Statement of scope, normative references, conformance requirements, and test methods(Section 1)(2) Conventions and definitions (Section 2)(3) Ass
44、ertions to test POSIX.1b 3 (Sections 2 through 15)(4) Conforming test results (Annex A)(5) Bibliography (Annex B)This introduction, any footnotes, notes accompanying the test, and the informative annexes arenot considered part of this standard. Annex A is normative. Annex B is informative.How to Rea
45、d This StandardThis document is organized using the same section numbering as POSIX.1b 3, in order tofacilitate finding the testing requirements for a particular element of POSIX.1b 3. Subclause1.4 has been added to this document to keep the section numbering consistent with POSIX.1b3 and to provide
46、 a place to describe features relevant to the test methods. It is stronglyrecommended that the reader review 1.4 after reading 1.1, 1.2, and this introduction. Wherepossible, this document tries to use the same assertion numbering that was used as IEEE Std2003.1-1992 4. This document skips over the
47、assertion numbers where there are no assertionsthat correspond to an assertion in IEEE Std 2003.1-1992 4. The assertions have beennumbered with a fractional part where more than one assertion takes the place of a singleassertion in IEEE Std 2003.1-1992 4.Amendment 1:2013 to CAN/CSA-ISO/IEC 14515-1-0
