[C] How to use ping library

Download ping library from ping library
configure & make & make install

Test Code :

#include <stdlib.h>
#include <stdio.h>
#include <oping.h>

int main(int argc, char **argv) {
    pingobj_t *ping;
    pingobj_iter_t *iter;

    if ((ping = ping_construct()) == NULL) {
        fprintf(stderr, "ping_construct failed\n");
        return (-1);
    }
    printf("ping_construct() success\n");

    if (ping_host_add(ping, "www.xively.com") < 0) {
        const char * errmsg = ping_get_error(ping);
        fprintf(stderr, "ping_host_add(www.xively.com) failed. %s\n", errmsg);
        return (-1);
    }
    printf("ping_host_add() success\n");

    while (1) {
        if (ping_send(ping) < 0) {
            fprintf(stderr, "ping_send failed\n");
            return (-1);
        }
        printf("ping_send() success\n");

        for (iter = ping_iterator_get(ping); iter != NULL; iter =
                ping_iterator_next(iter)) {
            char hostname[100];
            double latency;
            size_t len;

            printf("ping_iterator_get() success\n");
            len = 100;
            ping_iterator_get_info(iter, PING_INFO_HOSTNAME, hostname, &len);
            len = sizeof(double);
            ping_iterator_get_info(iter, PING_INFO_LATENCY, &latency, &len);

            printf("hostname = %s, latency = %f\n", hostname, latency);
        }
        sleep(1);
    }
    printf("exiting...\n");

    return (0);
}

Compile the code :
gcc -g -I/tmp/aaa/include/ -L/tmp/aaa/lib/ -Wl,-R/tmp/aaa/lib/ -loping -o a.out c.c

-Wl,-R look for library in /usr/local/lib at runtime before trying to use the one in /usr/lib/

Execute Code :
sudo ./a.out
