Parsing GET Variables

PaulS:

  char *name =strtok(NULL, "mode=blink&");

So, the delimiters are 'm', 'o', 'd', 'e', '=', 'b', 'l', 'i', 'n', 'k', and '&'. Does that really make sense?

i thought it makes sense because i know there is an string with that beginning.
so mode=blink&rate=30&color=yellow will then start at
rate=30&color=yellow.
After that i wanted to extract the 30 for example ( i don't know how long the value after rate= is)
