NETGetHostName

 
 

Library: Network utilities (OMNETUTL legacy)
Include: omnetutl.xin
Return type: String

Returns: Name of a host computer given its IP address.


Declaration

define external stream function NETGetHostName
   By-IP value string Host-IP optional

Argument definitions

Host-IP
is the dotted decimal format IP address of the host computer you want to retrieve the name of.


Purpose

Use NETGetHostName to retrieve the official name of a host computer given its Internet Protocol (IP) address.

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omnetutl.xin"

The IP address must be specified in dotted decimal format (for example, "127.0.0.1").

Example


  ; get the official host name given its IP
    
  include "omnetutl.xin"
  
  process
    local stream host
    set host to "206.116.41.138"
    output "ip of %g(host) is: <" || NETGetHostName By-IP host || ">%n"
  
    ; get the name of the local host
    ;
    output "Local host name is: <" || NETGetHostName || ">%n"
