I am having trouble progammically loging into an account.
I get an account status of 103. This is on UNIX but I assume that the same error code is returned regardless of the system. Any help or does anyone know where I can get more information on this type of coding???
The code is
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <errno.h>
