strtonum(3) doesn't behave like this. Anyway setting errno to 0 in a
library function would violate the C99 standard.
%%%
#include <err.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
int
main()
{
errno = EDOOFUS;
if (strtonum("1", 1, 10, NULL) == 0)
err(1, "failed");
printf("%d\n", errno);
return (0);
}
