Ok
-------- Start Code ---------------------------------
#include <sys/socket.h> // for connection api
#include <sys/types.h> // for predefined values
#include <netdb.h> // for hostname resolution api
char* host = "ftp.domain.com¡;
int port = 25;
struct sockaddr_in passive;
struct protoent * proto;
int skt;
proto = getprotobyname("tcp")
// gets the prototype number for tcp/ip
skt = socket(PF_INET, SOCK_STREAM, proto->p_proto );
//creates a socket
passive.sin_family = AF_INET;
// IPv4 connection type
passive.sin_addr = gethostbye(host);
// resolves the hostname and returns the correct in_addr
passive.sin_port = htons(port);
// htons changes the bit order so that it is in network format
connect(skt, &passive, sizeof(passive));
// connect to host
close(skt);
// close connection
-------- End Code -----------------------------------
this code does not check for errors and will probably crash if anything
goes wrong. How ever it does show how to connect to a server.
