Posix. 4 Programming for the Real World

Real-world programming (more typically called real-time programming) interacts with the "real world" of daily life in some way. Real-world programmers develop the unseen software that runs everything from the brakes in your car to your VCR. This software is typically characterized by deadlines - and harsh penalties if the deadlines aren't met. If the brake processor in your car doesn't meet a deadline, your car doesn't stop; if your ATM doesn't meet a deadline, you may start looking for another bank. When you've just rear-ended another car, it's no consolation that a sudden flurry of input slowed down your brake processor, so it couldn't react quickly enough when you hit the pedal. This book covers the POSIX.4 standard for portable real-time programming. But it goes well beyond a simple replication of the standard. It provides a general introduction to real-time programming and real-time issues: the problems software faces when it needs to interact with the real world, and how to solve them. If you're at all interested in real-time applications - which includes just about everything from telemetry to transaction processing - this book will be an essential reference.Gallmeister, Bill is the author of 'Posix. 4 Programming for the Real World' with ISBN 9781565920743 and ISBN 1565920740.
