CAN/CSA-ISO/IEC-9899-94 (R1999)

The international community has decided to make this standard available only in the English language version. It has been adopted as a National Standard of Canada on this basis. This National Standard of Canada is equivalent to International Standard ISO/IEC 9899:1990. 1 Scope This International Standard specifies the form and establishes the interpretation of programs written in the C programming language.¹ It specifies - the representation of C programs; - the syntax and constraints of the C programs; - the semantic rules for interpreting C programs; - the representation of input data to be processed by C programs; - the representation of output data produced by C programs; - the restrictions and limits imposed by a conforming implementation of C. This International Standard does not specify - the mechanism by which C programs are transformed for use by a data-processing system; - the mechanism by which C programs are invoked for use by a data-processing system; - the mechanism by which input data are transformed for use by a C program; - the mechanism by which output data are transformed after being produced by a C program; - the size or complexity of a program and its data will exceed the capacity of any specific data-processing system or the capacity of a particular processor; - all minimal requirements of a data-processing system that is capable of supporting a conforming implementation. ¹This International Standard is designed to promote the portability of c programs among a variety of data-processing systems. It is intended for use by implementors and programmers. It is accompanied by a Rationale document that explains many of the decisions of the Technical Committee that produced it.
