Yes.

Take a look at the following program and tell me how you'd detect an
error in a call to atoi().

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
char *good = "0";
char *bad = "bad";
printf("atoi(\"%s\") = %d\n", good, atoi(good));
printf("atoi(\"%s\") = %d\n", bad, atoi(bad));
return 0;
}

I can't really read that Keith but if I remember right this was
mentioned before but never really explained. I would've tried something
like this if it's even valid.
....
int i;
if (i=atoi(argv[1]))!=sizeof(int))
fprintf(stderr,"error\n");

*sigh* I dunno. Does this make any sense?
