Subj : STRTOK Question

I was messing around with strtok and found something interesting:

#include <string.h>
#include <stdio.h>

int main(void)
{
   char input[16] = "a,b,c,d";
   printf("%s %s %s %s\n", strtok(NULL , ","), strtok(NULL, ","), 
strtok(NULL, ","), strtok(input, ","));
   printf("%s %s %s %s\n", strtok(input, ","), strtok(NULL, ","), 
strtok(NULL, ","), strtok(NULL , ","));
   return 0;
}
/*
output:
d c b a
a (null) (null) (null)
*/


Is the first line of output a result of strtok, printf, or is strtok 
being misused? 
Why does the second line of output produce 3 (null) values?


Thanks,
Steve
