Function Documentation

ab_ga_il_wire_decode_route_cmd()

bool ab_ga_il_wire_decode_route_cmd	(	const uint8_t	frame[RBC_ENVELOPE_WIRE_SIZE],
		ab_ga_il_route_cmd_t *	out )

Decodes + fully range-validates an RBC_MSG_IL_ROUTE_CMD frame.

Parameters

[in]	frame	Raw RBC_ENVELOPE_WIRE_SIZE bytes; frame[0] must be RBC_MSG_IL_ROUTE_CMD.
[out]	out	Decoded payload on success; untouched on failure.

Returns

true only if frame[0] is the right kind AND every field is in range (enums within their declared value sets; identity fields -1 or >= 0; the two flags 0 or 1). false otherwise - a malformed or out-of-range command is rejected, not clamped.

ab_ga_il_wire_decode_status()

bool ab_ga_il_wire_decode_status	(	const uint8_t	frame[RBC_ENVELOPE_WIRE_SIZE],
		ab_ga_il_status_msg_t *	out )

Decodes + validates an RBC_MSG_IL_STATUS frame. Same contract.

ab_ga_il_wire_encode_route_indication()

void ab_ga_il_wire_encode_route_indication	(	uint8_t	frame[RBC_ENVELOPE_WIRE_SIZE],
		const ab_ga_il_route_indication_t *	in )

Encodes an RBC_MSG_IL_ROUTE_INDICATION frame (zero-fills the whole RBC_ENVELOPE_WIRE_SIZE slot first).

Parameters

[out]	frame	Receives the full slot.
[in]	in	Payload to encode. Assumed already valid (RBC-side producer).
