Your basic steps are:
//From the platform SDK code...
#define DEFAULT_PORT "5001" // Default listening port
#define DEFAULT_PROTO SOCK_STREAM // Default to TCP protocol
#define DEFAULT_BUFFER_LEN 4096 // Default recv buffer length
// Load Winsock

..
// Create the socket according to the parameters returned

// Bind the socket to the address returned

// If a TCP socket, call listen on it

//And then you create a thread to handle the listen
