        data->zoom = 10;
        data->depth = 5;
    }
    else
    {
        data->window_x = 1720;
        data->window_y = 900;

        data->depth = 4;
    }
}

i wanna short this code. I can create an extra function. but this function is forbidden to take more than 4 parameters. I need to place the values ​​that change according to the size of the map into my data.

CodePudding user response：

Perhaps, define an array of struct of type t_fdf:

struct t_fdf data[] = {
    {960, 540, 30, 20},
    {1280, 720, 20, 15},
    {1366, 786, 20, 10},
    {1600, 900, 10, 5},
    {1720, 900, 5, 4}
};

Then you can assign individual members of the array to the pointer. Much like how the GNU's getopt_long function works.

You might benefit from some more information about the function here: https://linux.die.net/man/3/getopt_long
