I understand I need use sockets to implement IRC's DCC protocol to my program. Here is the part I dont understand.

Here is a quick explanation on how DCC Works:

Data is sent in packets, rather than dumped in a stream manner. The recipient should acknowledge each packet by transmitting the total number of bytes received as an unsigned, 4 byte integer in network byte order.

My Question: How do I send the number of bytes I have received as an unsigned, 4 byte integer?

An Answer would be greately appreciated.

What software to manage TCP/IP are you using?. Something like DWinsock? or you are handling TCP "at Hand"?

What you need should be the htonl() function from the Winsock unit... at least i have it under Delphi 2.

Help on "htonl" gives:

--//--
The Windows Sockets htonl function converts a u_long from host to network byte order.

This function takes a 32-bit number in host byte order and returns a 32-bit number in network byte order.

u_long htonl (
  u_long hostlong
);

Parameters

hostlong
  A 32-bit number in host byte order.

Return Value

The htonl function returns the value in network byte order.
