Define new instance of browser in c

A interesting question!

Creating a new instance of a browser in C is not a straightforward task, as browsers are complex applications that require a lot of dependencies and infrastructure to run. However, I can provide you with some possible approaches:

1. Using a library: You can use a library that provides a C interface to a browser, such as:
   • webkit2gtk: A C library that provides a WebKit-based browser engine.
   • chromium Embedded Framework (CEF): A C++ library that provides a Chromium-based browser engine.
   • QtWebEngine: A C++ library that provides a Qt-based browser engine.

These libraries provide a C interface to create a new browser instance, but you'll need to link against the library and include its headers in your project.

2. Using a system call: You can use a system call to launch a new browser instance, such as:
   • system() function: This function executes a command in a subshell. You can use it to launch a browser by calling the browser's executable with the desired command-line arguments.
   • fork() and exec() functions: These functions allow you to create a new process and execute a new program in that process. You can use them to launch a browser by creating a new process and executing the browser's executable.

Here's an example of how you could use the system() function to launch a new browser instance:

#include <stdlib.h>

int main() {
    system("google-chrome --new-window https://www.example.com");
    return 0;
}

This code launches a new instance of Google Chrome with a new window and navigates to https://www.example.com.

3. Creating a custom browser: If you want to create a custom browser from scratch, you'll need to implement a browser engine, such as a rendering engine (e.g., WebKit or Blink) and a JavaScript engine (e.g., V8 or SpiderMonkey). This is a complex task that requires a deep understanding of browser architecture and a significant amount of code.

Keep in mind that creating a new instance of a browser in C is not a trivial task, and it may require a significant amount of code and expertise. If you're looking for a simpler solution, you may want to consider using a higher-level language or a library that provides a C interface to a browser.
