How to open the default web browser in Windows in C?

Question

In C in Windows, how do I open a website using the default browser? In Mac OS X, I do system(\"open http://url\");

Answer 1

To open a URL in your default browser you could use shell commands and system() like this:

#include 

int main(void)
{
  system("open https://example.com");
}

open is the default command to open stuff on MacOS, but what happens when you want to open a URL on Windows, Linux, or another operating system?

Well, you will need to change that open command.

On Linux

xdg-open 

On Windows

start 

On MacOS

open 

But there is good news, you don't need to handle that, I already created a module/package/library and you can install it using CLIB. It is cross-platform, already handle the operating systems stuff, and it is super easy to include it on your project.

Installation

$ clib install abranhe/opener.c

Usage

#include "opener.h"

int main(void)
{
    opener("https://example.com");
    return 0;
}

Since it is written using the shell commands, you are also able to open local directories.

// Open current directory
opener(".");
