The INET unit

The INET unit

The INET unit is designed to give you access to DNS routines in the C libraries of your linux system.

All the calls needed to get host entries based on IP numbers or host names are there: 

function GetHostEnt : PHostEnt;
function GetHostByName ( Name : Pchar) : PHostEnt;
function GetHostByAddr ( Addr : PHostAddr; Len : Longint; HType : Longint) : PHostEnt
procedure SetHostEnt (stayopen : longint);
procedure EndHostEnt;
function GetNetEnt : PNetEnt;
function GetNetByName ( Name : pchar) : PNetEnt;
function GetNetByAddr ( Net : Longint; NetType : Longint) : PNetEnt;
procedure SetNetEnt ( Stayopen : Longint);
procedure EndNetEnt;
function getservent : PServEnt;
function getservbyname (name : pchar  ; protocol : pchar) : PServEnt;
function getservbyport (port : longint; protocol : pchar) : PServEnt;
procedure setservent (StayOpen : longint);
procedure endservent;

Other than that, it implements three objects (THost, TService TNet) to do these lookups in a more pascal like manner.

Provided in the archive is a makefile and two testprograms, under which a finger client.

You can get the source of the unit in the packages source from the SVN repository. SVN contains a testprogram which shows what the unit can do, and how to use it.
