  • address: The numerical IPv4 address to be converted.
  • ipv6Address: The array used to store the converted IPv6 address as 16 byte array.

​
Return Values

  • 0xFFFFFF: The specified address string was invalid.
  • 0x0: The function completed successfully, the result is stored into an array.

Example

on start
{
  const dword IPV6_STR_SIZE = 40; // IPv6 string size
  int i;                         // loop variable
  byte ipv6Addr[16];             // IPv6 address bytes.
  dword result;                  // function result

  char ipv6AddrStr[IPV6_STR_SIZE] = "2001:DB8:85A3:8D3:1319:8A2E:370:7344";

  write("Converting IPv6 Address %s to bytes...", ipv6AddrStr);

  result = IpGetAddressAsArray( ipv6AddrStr, ipv6Addr );
  if (result == 0)
  {
    // success...
    write("IpGetAddressAsArray: returned array with IPv6 bytes:");
    for ( i=0; i<16; i++)
    {
      write("Byte %.2d = 0x%.2x", i, ipv6Addr[i]);
    }
  }
  else
  {
    writeLineEx(1, 3, "IpGetAddressAsArray: The specified address string was invalid.");
  }
