One ping only

For some odd reason, today was the day when I woke up and continued working on libICMP. It’s now almost seven years since I first adopted Tim Lawless’ public domain version, and today I picked up where I left off and started refactoring and cleaning up.

Example:

#include "icmp/icmp.h"

int main(int argc, char *argv[])
{
    char *host = "localhost";
    struct libicmp *obj;
    
    if (argc >= 2)
            host = argv[1];

    if (!(obj = icmp_open(host, 0x1337, 0)))
            return 1;
    
    return icmp_ping(obj, 0, 0) == -1;
}

libICMP is nowhere near as fancy as liboping and is only slightly smaller with a more liberal license (ISC). The first release is however available from GitHub. Pull requests are as usual most welcome! :smiley:
