What is the purpose of gtk_init function?

The gtk_init() function is used to initialize the GTK library in a GTK application. Its primary purposes are:

1. Initialize GTK: It sets up the GTK environment, preparing it for use.
2. Process Command-Line Arguments: It can take command-line arguments to handle options that affect the behavior of the GTK application.

Typically, you call gtk_init() at the beginning of your main() function before creating any GTK widgets. Here's a simple example:

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {
    gtk_init(&argc, &argv); // Initialize GTK

    // Your GTK application code here

    return 0;
}

This function ensures that GTK is ready to create windows, handle events, and manage the user interface. If you have more questions about GTK or need further clarification, feel free to ask!
