Function Documentation

socket_dequeue_packet()

struct packet * socket_dequeue_packet

(

struct socket *

socket

)

If the queue is empty, return NULL.

socket_enqueue_packet()

error_t socket_enqueue_packet	(	struct socket *	socket,
		struct packet *	packet
	)

Packets received can be read by the user using the recv syscall.

socket_from_vnode()

static struct socket * socket_from_vnode ( struct vnode *  vnode )

inlinestatic

Returns

The socket corresponding to a vnode

socket_init()

error_t socket_init	(	struct socket *	socket,
		int	domain,
		int	type,
		int	proto
	)

Parameters

domain	Communication domain (AF_*).
type	Connection type (SOCK_STREAM, ...).
proto	Packet protocol type

socket_node()

static struct vnode * socket_node ( struct socket *  socket )

inlinestatic

Returns

The socket's vnode
