Help¶

With TRC_CFG_SNAPSHOT_MODE set to TRC_SNAPSHOT_MODE_RING_BUFFER, the
events are stored in a ring buffer, i.e., where the oldest events are
overwritten when the buffer becomes full. This allows you to get the last
events leading up to an interesting state, e.g., an error, without having
to store the whole run since startup.

When TRC_CFG_SNAPSHOT_MODE is TRC_SNAPSHOT_MODE_STOP_WHEN_FULL, the
recording is stopped when the buffer becomes full. This is useful for
recording events following a specific state, e.g., the startup sequence.
