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);
}
%%%

$ cc test.c
$ ./a.out
