mistake in example in getrlimit(2)

here is example from getrlimit(2):

#define _GNU_SOURCE
#define _FILE_OFFSET_BITS 64
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/resource.h>

#define errExit(msg) do { perror(msg); exit(EXIT_FAILURE); \
} while (0)

int
main(int argc, char *argv[])
{
    struct rlimit old, new;
    struct rlimit *newp;
    pid_t pid;

    if (!(argc == 2 || argc == 4)) {
 fprintf(stderr, "Usage: %s <pid> [<new-soft-limit> "
  "<new-hard-limit>]\n", argv[0]);
 exit(EXIT_FAILURE);
    }

    pid = atoi(argv[1]); /* PID of target process */

    newp = NULL;
    if (argc == 4) {
 new.rlim_cur = atoi(argv[2]);
 new.rlim_max = atoi(argv[3]);
 newp = &new;
    }

    /* Set CPU time limit of target process; retrieve and display
       previous limit */

    if (prlimit(pid, RLIMIT_CPU, newp, &old) == -1)
 errExit("prlimit-1");
    printf("Previous limits: soft=%lld; hard=%lld\n",
     (long long) old.rlim_cur, (long long) old.rlim_max);

    /* Retrieve and display new CPU time limit */

    if (prlimit(pid, RLIMIT_CPU, NULL, &old) == -1)
 errExit("prlimit-2");
    printf("New limits: soft=%lld; hard=%lld\n",
     (long long) old.rlim_cur, (long long) old.rlim_max);

    exit(EXIT_FAILURE);
}

As you can see, this program will always exit with EXIT_FAILURE status. It will be clearer and more correct to replace last line with "exit(EXIT_SUCCESS);"
