gateway_c_il_handler_broadcast_to_ab()

void gateway_c_il_handler_broadcast_to_ab

(

bytes[RBC_ENVELOPE_WIRE_SIZE]

)

Sends one RBC_ENVELOPE_WIRE_SIZE frame to BOTH A and B on the IL relay link. Used by gateway_c_logctl.c to fan a diagnostic RBC_MSG_SET_LOG_LEVEL control frame out to the pair; the IL link is the one C<->AB link A/B always poll from C (Train is bidirectional, CTC is AB->C only). Best-effort: a send error is logged, not returned.
