fr_bio_fd_s

struct fr_bio_fd_s

Our FD bio structure.

Definition at line 40 of file fd_priv.h.

Collaboration diagram for fr_bio_fd_s:

Data Fields
uint8_t *	accept_buffer	A LISTEN datagram bio reads datagrams into this buffer, which is allocated once by fr_bio_fd_init_listen().
struct fr_bio_fd_s.connect	connect
uint8_t *	first_datagram	The datagram which fr_bio_fd_accept() read to name the peer. Only fr_bio_fd_read_first_datagram() reads it.
size_t	first_datagram_len	Length of first_datagram.
	FR_BIO_COMMON
fr_bio_fd_info_t	info
int	max_tries	how many times we retry on EINTR
size_t	offset	where fr_bio_fd_packet_ctx_t is stored
struct sockaddr_storage	remote_sockaddr	for connected UDP sockets.
socklen_t	remote_sockaddr_len

fr_bio_fd_s.connect

struct fr_bio_fd_s.connect

Definition at line 48 of file fd_priv.h.

Data Fields
fr_event_list_t *	el	for fr_bio_fd_connect()
fr_bio_callback_t	error	for fr_bio_fd_connect()
fr_timer_t *	ev	for fr_bio_fd_connect()
fr_bio_callback_t	success	for fr_bio_fd_connect()
fr_bio_callback_t	timeout	for fr_bio_fd_connect()
