on start
{
  const dword STR_SIZE = 256; // string buffer size
  char ifDescr[STR_SIZE];     // Interface description string.
  dword ifIdx;                // interface index
  long result;                // function result.

  for (ifIdx = 1; ifIdx <= IpGetAdapterCount(); ifIdx++)
  {
    result = IpGetAdapterDescription( ifIdx, ifDescr, elcount(ifDescr) );
    if (result == 0)
    {
      // success.
      write("IpGetAdapterDescription for adapter %d returned: %s", ifIdx, ifDescr);
    }
