fgetarg and freadln

[Ni3ls]

Hi all,

We have 2 commands for reading scriptdata. But what is exactly the difference? With fgetarg you can read a certain argument, but what does freadln do exactly?

freadln just reads the amount of args on a line and skips to the next line after (first freadln doesnt actually skip to the next line, else you wouldnt be able to get the argcount on line 1 AND read the args)

But how to use freadln properly? And is it even that usefull?

		readfile(filename)
{
    result = [];
    fid = openfile(filename, "read");
    if(fid == -1)
        return undefined;
    linenum = 0;
    argcount = freadline(fid);
    while(argcount > -1)
    {
        result[linenum] = [];
        for(i = 0; i < argcount; i++)
            result[linenum][result[linenum].size] = fgetarg(fid, i);
        argcount = freadline(fid);
    }
    closefile(fid);
    return result;
}

So for example when I have a file like this

1234, 1245, 1236, 234645, 131233,

How can I read all those values and store them in an array?

		readthatfile()
{
    f = openfile("thatfile.txt", "read");
    if(f == -1)
        return;
    argcount = freadln(f);
    if(argcount == -1) //end of file
        return;
    result = [];
    for(i = 0; i < argcount; i++)
    {
        result[i] = fgetarg(f, i);
    }
    closefile(f);
    return result;
}

Works perfectly!
