	Send data to the transport.

ssize_t(*	recv )(struct UDSTp hdl, uint8_t buf, size_t bufsize, UDSSDU_t *info)
	Receive data from the transport.

UDSTpStatus_t(*	poll )(struct UDSTp *hdl)

Detailed Description

UDS Transport layer.

Note: implementers should embed this struct at offset zero in their own transport layer handle

UDSTpStatus_t(* UDSTp_t::poll) (struct UDSTp *hdl)

Poll the transport layer.

Parameters

hdl	pointer to transport handle

Note: the transport layer user is responsible for calling this function periodically; threaded implementations like linux isotp sockets don't need to do anything here.

Returns: UDS_TP_IDLE if idle, otherwise UDS_TP_SEND_IN_PROGRESS or UDS_TP_RECV_COMPLETE

Definition at line 282 of file iso14229.h.

ssize_t(* UDSTp_t::recv) (struct UDSTp *hdl, uint8_t *buf, size_t bufsize, UDSSDU_t *info)

Receive data from the transport.

Parameters

hdl	transport handle
buf	receive buffer
bufsize	size of the receive buffer
info	pointer to SDU info to be updated by transport implementation. May be NULL. If non-NULL, the transport implementation must populate it with valid values.

ssize_t(* UDSTp_t::send) (struct UDSTp *hdl, uint8_t *buf, size_t len, UDSSDU_t *info)

Send data to the transport.

Parameters

hdl	pointer to transport handle
buf	a pointer to the data to send
len	length of data to send
info	pointer to SDU info (may be NULL). If NULL, implementation should send with physical addressing
