Functions
int	sock_error_occurred (struct sock_state_t *s)
Communication functions
These are for sending and receiveing. sending return 0 if ok, negative if error, receiving return # received byte or negative if error
int	sock_send (struct sock_state_t *s, char *buffer)
	send buffer on s, remember that "\r\n" will be appended to buffer
int	sock_sendraw (struct sock_state_t *s, const char *buffer)
	send buffer on s, with no "\r\n" at the end
int	sock_receive (struct sock_state_t *s, char *buffer, int maxlen)
	send a non terminated buffer of len l on s, with no "\r\n" at the end
int	sock_receive_with_timeout (struct sock_state_t *s, char *buffer, int maxlen, int timeout)
	receive with timeout in seconds
Client/Server functions
These are for starting a client or a server.
struct sock_state_t *	sock_connect (char *hostname, unsigned long port, int maxlinelen, void(*print)(char *))
	connect to a server
void	sock_disconnect (struct sock_state_t *s)
	close the socket and free the structure s
struct sock_state_t *	sock_bind (struct in_addr bind_add, unsigned short port, int maxlinelen, void(*print)(char *))
	bind a socket and listen on it
struct sock_state_t *	sock_listen (struct sock_state_t *s)
	this is the accept, returns the new socket that must be freed by the caller

[read]

this is the accept, returns the new socket that must be freed by the caller

int sock_receive	(	struct sock_state_t *	s,
		char *	buffer,
		int	maxlen
	)

send a non terminated buffer of len l on s, with no "\r\n" at the end

int sock_receive_with_timeout	(	struct sock_state_t *	s,
		char *	buffer,
		int	maxlen,
		int	timeout
	)

receive with timeout in seconds

int sock_send	(	struct sock_state_t *	s,
		char *	buffer
	)

send buffer on s, remember that "\r\n" will be appended to buffer

int sock_sendraw	(	struct sock_state_t *	s,
		const char *	buffer
	)

send buffer on s, with no "\r\n" at the end
