The method of embedding the C language in the Go language

This article demonstrates an example of how to embed the C language in the Go language. Share with you for your reference. The specific analysis is as follows:

The Go language official has a tool called cgo, which makes it easy to embed the C code in the Go language code or to integrate the C and Go codes. Here is a simple piece of C experiment code embedded in Go:

package main

/*

#include <stdio.h>

#include <stdlib.h>

void say_hello() {

        printf("Hello World!\n");

}

*/

import "C"

func main() {

        C.say_hello()

}

Save the above code to ctest.go and run go run ctest.go to see the effect immediately.

It is convenient to call a function written by C in Go code without having to implement a special interface or declare anything yourself.

I hope this article has been helpful to your programming of Go language.
