Description

Blocks the current thread until all tasks captured by the event are complete. For details, see the event capture details in acl.rt.record_event.

This API is enhanced based on acl.rt.synchronize_event. You can set permanent waiting or a specific timeout period. If a specific timeout period is configured, the application automatically exits when an exception occurs.

Prototype
