Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Integration with Go

The Go programming language (or simply Golang) has an easy integration with native shared libraries. It can be considered as the next generation of the C and C++ programming languages and it calls itself a system programming language. Therefore, we expect to load and use the native libraries easily when using Golang.

In Golang, we use a built-in package called cgo to call C code and load the shared object files. In the following Go code, you see how to use the cgo package and use it to call the C functions loaded from the C stack library file. It also defines a new class, Stack, which is used by other Go code to use the C stack functionalities:

package main
/*
#cgo CFLAGS: -I..
#cgo LDFLAGS: -L.. -lcstack
#include "cstack.h"
*/
import "C"
import (
  "fmt"
)
type Stack struct {
  handler *C.cstack_t
}
func NewStack() *Stack {
  s := new(Stack)
  s.handler = C.cstack_new()
  C.cstack_ctor(s.handler, 100)
  return s
}
func (s *Stack...
