Author Description

- This book aims at making readers a programming expert and an excellent software architect using portable standard POSIX APIs at the operating system API level. It offers a very systematic education of all required knowledge, concepts, technologies, techniques, skills and problem solutions for programming at the system level. - This book contains the knowledge, skills and training that a computer science/engineering or software engineering student must have. - It's a book that one must read if you are a software engineer developing system software in operating systems, database management systems, distributed systems, clustered systems, networking software, computer network security and client-server applications. - This book is intended as a textbook for system programming course at college, either a one-year System Programming course or a one-semester System Programming followed by another semester of Network Programming. It is also a reference or self-study guide for computer software engineers already working in the industry. - This book contains the best of author's 30+ years of experience across many fields in the U.S. computer software industry. - It features software design principles and programming tips for developing first-class software and author's definition of first-class software. - Author presents elegant and very simple solutions for many common real-world problems such as update loss, cross-endian, alignment, backward and forward compatibility, socket applications, distributed applications, network security and PKI. - Following are some of the highlights from the book. - Pthreads programming. Using pthread local storage to solve reentrant deadlock problems, using mutex and condition variables to solve producer-consumer problems. Fix dangling mutex using robust mutex. Thread cancellation points. - Concurrency control using the fastest locking routines of your own to gain performance improvements up to 80+%, System V and POSIX semaphores, ways to p
