Function Documentation

int kre_net_connect	(	struct socket *	s,
		struct sockaddr_in *	a
	)

Connect to server with addres a using socket s.

Parameters:

	s	Socket
	a	Addres

Returns:

error code or 0

void kre_net_set_addr	(	struct sockaddr_in *	a,
		u8	ip[],
		int	port
	)

Set addres to ip and port.

Parameters:

	a	Pointer to addres which we set.
	ip	IP addres to set.
	port	Port number to set.

void kre_net_set_local	(	struct sockaddr_in *	a,
		int	port
	)

Set addres to 0.0.0.0 and port to port.

Parameters:

	a	Addres to set.
	port	Port number.

int kre_net_sock_accept	(	struct socket *	srv,
		struct socket **	cli
	)

Accepting client TCP request.

Parameters:

	srv	Pointer to server socket.
	cli	Pointer to pointer client socket.

int kre_net_sock_bind	(	struct socket *	s,
		struct sockaddr_in *	a
	)

Binding addres structure with socket.

Parameters:

	s	Socket to bind.
	a	Addres structure to bind.

int kre_net_sock_listen

(

struct socket *

s

)

Turn on listening on socket.

Parameters:

s

Socket which should listen.

int kre_net_sock_receive	(	struct socket *	s,
		struct sockaddr_in *	a,
		unsigned char *	buf,
		int	len
	)

Receive len bytes from client socket s.

Parameters:

	s	Client socket.
	a	Client addres.
	buf	Buffer to handle data from client.
	len	Max bytes to get from client.

int kre_net_sock_send	(	struct socket *	s,
		struct sockaddr_in *	a,
		unsigned char *	buf,
		int	len
	)

Sending data to client socket.

Parameters:

	s	Client socket.
	a	Cut addres to send to the client.
	buf	Data buffer which will be send to the client.
	len	Count of byte from data buffer which will be send to the client.

int kre_net_sock_setopt_reuse

(

struct socket *

s

)

Set one of the socket options.

REUSEADDR = 1 this is not work and need recognition.
