Explore the fundamentals of systems programming starting from kernel API and filesystem to network programming and process communicationsKey FeaturesLearn how to write Unix and Linux system code in Golang v1.12Perform inter-process communication using pipes, message queues, shared memory, and semaphoresExplore modern Go features such as goroutines and channels that facilitate systems programmingBook 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 learnExplore concepts of system programming using Go and concurrencyGain insights into Golang s internals, memory models and allocationFamiliarize yourself with the filesystem and IO streams in generalHandle and control processes and daemons lifetime via signals and pipesCommunicate with other applications effectively using a networkUse various encoding formats to serialize complex data structuresBecome well-versed in concurrency with channels, goroutines, and syncUse concurrency patterns to build robust and performant system applicationsWho this book is forIf you are a developer who wants to learn system programming with Go, this book is for you. Although no knowledge of Unix and Linux system programming is necessary, intermediate knowledge of Go will help you understand the concepts covered in the book
