Wireshark · Ethereal-dev: [Ethereal-dev] What that arrays of structs like udphstruct for

[Andy Howell <AndyHowell@xxxxxxxxxxxxx>]

One little thing that has been bothering me is why do the dissectors 
have a construct like:

  static e_udphdr udphstruct[4], *udph;
  static int udph_count=0;

  udph_count++;
  if(udph_count>=4){
     udph_count=0;
  }
  udph=&udphstruct[udph_count];
