Previous Table of Contents "New C Standard" commentary
0 With the introduction of new devices and extended character sets, new features may be added to this International Standard. Subclauses in the language and library clauses warn implementors and programmers of usages which, though valid in themselves, may conflict with future additions.
Certain features are obsolescent, which means that they may be considered for withdrawal in future revisions of this International Standard. They are retained because of their widespread use, but their use in new implementations (for implementation features) or new programs (for language [6.11] or library features [7.26]) is discouraged.
This International Standard is divided into four major subdivisions:
preliminary elements (clauses 14);
the characteristics of environments that translate and execute C programs (clause 5);
the language syntax, constraints, and semantics (clause 6);
the library facilities (clause 7).
Examples are provided to illustrate possible forms of the constructions described. Footnotes are provided to emphasize consequences of the rules described in that subclause or elsewhere in this International Standard. References are used to refer to other related subclauses. Recommendations are provided to give advice or guidance to implementors. Annexes provide additional information and summarize the information contained in this International Standard. A bibliography lists documents that were referred to during the preparation of the standard.
The language clause (clause 6) is derived from The C Reference Manual.
The library clause (clause 7) is based on the 1984 /usr/group Standard.
