title: Assembly, multiple arguments -m32 / linux (same as stdarg in C)
body: <p>To solve this, I understand C, and I'm still a beginner in Assembly so I'm kinda stuck with a little problem here.</p>
  
  <p>I'm having some trouble with taking multiple arguments, maybe count them if I should do that, and use the format arguments in my assembly code.</p>
  
  <p>Trying to add some bytes to a string with many arguments. I know how to put the two first arguments on the stack, but the other arguments after the first is the format (like %s, %d, %c etc) and the first argument is the one that is supposed to be the variable i want to write to.
  In C, standard main has argument-counter. I might want to count the arguments here aswell!? How can I do that, if that's how It's done?</p>
