This is a modified version of a Ping library originally written by Blake Foster (http://blake-foster.com/contact.php) that can be downloaded here: http://www.blake-foster.com/projects/ICMPPing.zip

I modified it to return just the useful bits of information suitable for parsing.

Example:

  #include <ICMPPing.h>

  byte theIp[] = { 192, 168, 1, 1 };
  char returnBuffer[20];
  int timeout = 4; // seconds
  SOCKET pingSocket = 3;
  
  ICMPPing ping(pingSocket);
  
  ping(timeout, theIp, returnBuffer);
  
  if (strncmp(returnBuffer, "T", 1) == 0)
  {
      // ping timed out
  }
  
  if (strncmp(returnBuffer, "F", 1) == 0)
  {
      // ping failed
  }
  
  // returnBuffer contains something like "32|104|200"
  //                                       ^  ^   ^
  //                                       |  |   |
  // Request size --------------------------  |   |
  // Ping time in milliseconds ----------------   |
  // Time to live in milliseconds -----------------

  
ICMPPing.cpp:52

    Changed:
        sprintf(result, "sendEchoRequest failed.");
    
    To:
        sprintf(result, "F");

ICMPPing.cpp:62

    Changed:
        sprintf(result, "Reply[%d] from: %d.%d.%d.%d: bytes=%d time=%ldms TTL=%d", i + 1, replyAddr[0], replyAddr[1], replyAddr[2], replyAddr[3], REQ_DATASIZE, time, TTL);
    
    To:
        sprintf(result, "%d|%ld|%d", REQ_DATASIZE, time, TTL);
        
ICMPPing.cpp:68

    Changed:
        sprintf(result, "Request Timed Out");
        
    To:
        sprintf(result, "T");
