Preface

This manual describes:

The information is presented as a series of articles, each covering a specific transition topic. These articles were originally written for an in-house AT&T newsletter by David Prosser, Distinguished Member of Technical Staff, AT&T Bell Laboratories. Comments by Vijay Tatkar and Walter Nielsen of Sun Microsystems, Inc. have also been incorporated.

Appendix A, "K&R Sun C / Sun ANSI C Differences," contains much of the information from these articles in tabular form.

For more information on programming in ANSI C, refer to the following manuals:

We recommend two texts for programmers new to the C language: Kernighan and Ritchie (hereinafter referred to as K&R), The C Language, Second Edition, 1988, Prentice-Hall; Harbison and Steele, C: A Reference Manual, Second Edition, 1987, Prentice-Hall. For implementation-specific details not covered in this book, refer to the Application Binary Interface for your machine.
