what does this line of code mean?

what does this line of code mean exactly?

p = strtok(line_in, " \t<>\n");

>p = strtok(line_in, " \t<>\n");
Take the first sequence of characters from line_in up to a tab, opening angle bracket, closing angle bracket or newline and assign the address of the beginning of that sequence to p.

ok whats another way to write this:

for (i = 0; i < margin; putchar(' '), i++) ;

>for (i = 0; i < margin; putchar(' '), i++) ;
I'd prefer

Code:

---

for (i = 0; i < margin; i++)
    putchar(' ');

But you can write it a lot of ways depending on what type of loop you use.

Why not just look at the manual to find out what functions do. :)
