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...
