3.2 GetServlist OS X Example

GetServList() function could be written in the following way:

void GetServerList()
{
    json_object *j_obj;
    char szCmd[1024];
    j_obj = json_object_new_object();
    json_object_object_add(j_obj, "cmd", json_object_new_int(OVS_CMD_GET_SERVLIST));
    snprintf(szCmd, sizeof(szCmd), "%s", json_object_get_string(j_obj));
    json_object_put(j_obj);
    CmdProc(szCmd);
}

Result will be returned via callback as a JSON:

code will be OVS_NOTIFY_GET_SERVLIST

err will be OVS_ERR_OK in case of success

data will be an object of the following structure:

{
    "U.S. New York": [
      {
        "ip": "104.192.3.90"
      },
      {
        "tcp_ports": [
          "1194",
          "8080",
          "8181"
        ]
      },
      {
        "udp_ports": [
          "1194",
          "8080",
          "8181"
        ]
      },
      {
        "flag": "url/us.png"
      }
    ]
  }
