This book provides information on application programming interfaces to the operating system.
This book is part of the six-volume technical reference set, AIX 5L Version 5.1 Technical Reference, that provides information on system calls, kernel extension calls, and subroutines in the following volumes:
This book is intended for experienced C programmers. To use the book effectively, you should be familiar with commands, system calls, subroutines, file formats, and special files.
The following highlighting conventions are used in this book:
| Bold | Identifies commands, subroutines, keywords, files, structures, directories, and other items whose names are predefined by the system. Also identifies graphical objects such as buttons, labels, and icons that the user selects. |
| Italics | Identifies parameters whose actual names or values are to be supplied by the user. |
| Monospace | Identifies examples of specific data values, examples of text similar to what you might see displayed, examples of portions of program code similar to what you might write as a programmer, messages from the system, or information you should actually type. |
ISO 9000 registered quality systems were used in the development and manufacturing of this product.
Beginning with Version 4.3, the operating system is designed to
support The Open Group's UNIX98 Specification for portability of
UNIX-based operating systems. Many new interfaces, and some current
ones, have been added or enhanced to meet this specification, making Version
4.3 even more open and portable for applications.
At the same time, compatibility with previous releases of the operating
system is preserved. This is accomplished by the creation of a new
environment variable, which can be used to set the system environment on a
per-system, per-user, or per-process basis.
To determine the proper way to develop a UNIX98-portable application, you may
need to refer to The Open Group's UNIX98 Specification, which can be
obtained on a CD-ROM by ordering Go Solo 2: The Authorized Guide to
Version 2 of the Single UNIX Specification, ISBN: 0-13-575689-8, a
book which includes The Open Group's UNIX98 Specification on a
CD-ROM.
