# $EPIC: longtoip.txt,v 1.2 2006/08/01 04:07:08 sthalik Exp $
======Synopsis:======
$longtoip(<integer>)

======Technical:======
   * If the <integer> value is omitted the empty string is returned.
   * The <integer> value is taken to be a 32 bit unsigned integer.
   * The <integer> value is taken to be in NETWORK ORDER.
   * The return value is the dotted-quad IP address of <integer>

======Practical:======
This function does the reverse of $[[iptolong]]().  The DCC handshake uses
'long's to swap ip addresses.  You can use this function to convert the 'long'
into a dotted-quad IP address which can then be converted into a hostname by
the $[[convert]]() function.  This can be used to look up the hostname of
someone offering you a DCC connection.

======Returns:======
The dotted-quad IP address equivalent of <integer>

======Examples:======
<file>
$longtoip(2131231747)                                returns "127.8.4.3"
$longtoip(${(127 << 24) + (8 << 16) + (4 << 8) + 3}) returns "127.8.4.3"
