Detailed Description

Transport driver API callbacks.

Field Documentation

init

int(* fido2_transport_api::init) (fido2_transport_recv_cb_t cb, fido2_transport_cancel_cb_t cancel_cb)

Initialize the transport.

Called once during subsystem startup. The transport must store the callbacks and invoke them on every received CBOR message or cancel command.

Parameters

cb	Callback to invoke when a CBOR message is received.
cancel_cb	Callback to invoke when the cancel command is received

Return values

0	If successful.
-ENODEV	If hardware is not available.

notify

void(* fido2_transport_api::notify) (uint32_t cid, enum fido2_wire_status status)

Notify the transport of an operation progress change.

Called by the FIDO2 core to signal state transitions during long-running operations. Each transport translates this into the appropriate wire-protocol signaling.

Parameters

cid	Channel/connection identifier.
status	Progress status indicating what the core is doing.

send

int(* fido2_transport_api::send) (uint32_t cid, const uint8_t *data, size_t len)

Send response data to the host.

Parameters

cid	Transport channel ID to send the response on.
data	Response payload bytes.
len	Length of data in bytes.

Return values

0	If successful.
-EIO	On transport error.

shutdown

void(* fido2_transport_api::shutdown) (void)

Shut down the transport.
