Explore the fundamentals of systems programming starting from kernel API and filesystem to network programming and process communications
Key Features
Learn how to write Unix and Linux system code in Golang v1.12
Perform inter-process communication using pipes, message queues, shared memory, and semaphores
Explore modern Go features such as goroutines and channels that facilitate systems programming
Book DescriptionSystem software and applications were largely created using low-level languages such as C or C++. Go is a modern language that combines simplicity, concurrency, and performance, making it a good alternative for building system applications for Linux and macOS.
This Go book introduces Unix and systems programming to help you understand the components the OS has to offer, ranging from the kernel API to the filesystem. You'll then familiarize yourself with Go and its specifications. You'll also learn how to optimize input and output operations with files and streams of data, which are useful tools in building pseudo-terminal applications. You'll gain insights into how processes communicate with each other, and learn about processes and daemon control using signals, pipes, and exit codes. This book will also enable you to understand how to use network communication using various protocols, including TCP and HTTP. As you advance, you'll focus on Go's best feature - concurrency, which will help you handle communication with channels and goroutines, other concurrency tools to synchronize shared resources, and the context package to write elegant applications.
By the end of this book, you will have learned how to build concurrent system applications using GoWhat you will learn
Explore concepts of system programming using Go and concurrency
Gain insights into Golang s internals, memory models and allocation
Familiarize yourself with the filesystem and IO streams in general
Handle and control processes and daemons lifetime via signals and pipes
Communicate with other applications effectively using a network
Use various encoding formats to serialize complex data structures
