int net_accept	(	int	bind_fd,
		int *	client_fd,
		void *	client_ip
	)

Accept a connection from a remote client.

Returns:

0 if successful, XYSSL_ERR_NET_ACCEPT_FAILED, or XYSSL_ERR_NET_WOULD_BLOCK is bind_fd was set to non-blocking and accept() is blocking.

int net_bind	(	int *	fd,
		char *	bind_ip,
		int	port
	)

Create a listening socket on bind_ip:port. If bind_ip == NULL, all interfaces are binded.

Returns:

0 if successful, or one of: XYSSL_ERR_NET_SOCKET_FAILED, XYSSL_ERR_NET_BIND_FAILED, XYSSL_ERR_NET_LISTEN_FAILED

int net_recv	(	void *	ctx,
		unsigned char *	buf,

	)

Read at most 'len' characters. len is updated to reflect the actual number of characters read.

Returns:

This function returns the number of bytes received, or a negative error code; XYSSL_ERR_NET_TRY_AGAIN indicates read() is blocking.

	)

Write at most 'len' characters. len is updated to reflect the number of characters _not_ written.

Returns:

This function returns the number of bytes sent, or a negative error code; XYSSL_ERR_NET_TRY_AGAIN indicates write() is blocking.

Note:

Real amount of time slept will not be less than select()'s timeout granularity (typically, 10ms).
