Information technology - Programming languages - C

This document specifies the form and establishes the interpretation of programs written in the C programming language. It is designed to promote the portability of C programs among a variety of data-processing systems. It is intended for use by implementers and programmers. It specifies:

 

— the representation of C programs;

 

— the syntax and constraints of the C language;

 

— 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 document 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 that 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.

 

Annex J gives an overview of portability issues that a C program can encounter.
