"The first edition of this book has always been kept within arm's reach of my desk due to the wonderful explanations of all areas of the Linux userspace API. This second edition greatly overshadows the first one, and will replace it."
--Greg Kroah-Hartman, Linux kernel programmer

Develop Software that Leverages the Full Power of Today's Linux

Linux Application Development, Second Edition, is the definitive reference for Linux programmers at all levels of experience, including C programmers moving from other operating systems. Building on their widely praised first edition, leading Linux programmers Michael Johnson and Erik Troan systematically present the key APIs and techniques you need to create robust, secure, efficient software or to port existing code to Linux.

This book has been fully updated for the Linux 2.6 kernel, GNU C library version 2.3, the latest POSIX standards, and the Single Unix Specification, Issue 6. Its deep coverage of Linux-specific extensions and features helps you take advantage of the full power of contemporary Linux. Along the way, the authors share insights, tips, and tricks for developers working with any recent Linux distribution, and virtually any version of Unix.

****** INTERNATIONAL ORDERS ******
****** VERY IMPORTANT! ******

Travel time on International orders via regular parcel post can take up to 8 WEEKS to arrive. It averages 20-30 days, with some packages arriving faster than that, but 35+ day travel time is VERY common and quite normal, and can even be a bit longer if the package is held up in the Customs Department in your country waiting to be cleared for delivery.

The countries that take the longest are....
RUSSIA & UKRAINE (VERY LONG 50 to 60 days, even for PRIORITY MAIL!)
BRAZIL (40-50 days)
ITALY (35-45 days)
GERMANY (25-35 days)
AUSTRALIA (30-40 days of late for some unknown reason, however, this is not normal).

I do thank you for your patience. Airmail times are of course speedier.
