Function Documentation

cace_amp_proxy_msg_recv()

int cace_amp_proxy_msg_recv	(	int	sock_fd,
		cace_ari_t *	src,
		m_bstring_t	data
	)

Receive a message via datagram socket proxy from an ultimate source.

Parameters

	sock_fd	The socket file descriptor. The socket must be ready for reading (e.g. determined via poll() and POLLIN event) before this call.
[out]	src	The ultimate source endpoint being received from.
[out]	data	The data to populate, which must already be initialized.

Returns

Zero if successful, non-zero if reception is no longer possible.

cace_amp_proxy_msg_send()

int cace_amp_proxy_msg_send	(	int	sock_fd,
		const cace_ari_t *	dst,
		const uint8_t *	data_ptr,
		size_t	data_len
	)

Send a message via datagram socket proxy to an ultimate destination.

Parameters

	sock_fd	The socket file descriptor. The socket must be ready for writing (e.g. determined via poll() and POLLOUT event) before this call.
[in]	dst	The ultimate destination endpoint to send to.

Returns

Zero if successful, non-zero if sending is no longer possible.
