BloombergLP::bdlmt::EventScheduler::cancelEventAndWait

Declared in <bdlmt_eventscheduler.h>

Cancel the event having the specified handle. Block until the event having handle (if it is valid) is either successfully canceled or dispatched before the call returns. Return 0 on successful cancellation, and a non‐zero value if handle is invalid or if the event has already been dispatched or canceled. The behavior is undefined if this method is invoked from the dispatcher thread. Note that if the event is being executed when this method is invoked, this method will block until it is completed and then return a nonzero value.

0 on successful cancellation, and a non‐zero value otherwise
