- A timed_entry_call issues an entry call that is cancelled if the call (or
a requeue-with-abort of the call) is not selected before the expiration time
- For the execution of a timed_entry_call, the entry_name and the actual parameters
are evaluated, as for a simple entry call (see 9.5.3).
The expiration time (see 9.6) for the call is determined
by evaluating the delay_expression of the delay_alternative; the entry call
is then issued.
- If the call is queued (including due to a requeue-with-abort), and not
selected before the expiration time is reached, an attempt to cancel the call
is made. If the call completes due to the cancellation, the optional
sequence_of_statements of the delay_alternative is executed; if the entry
call completes normally, the optional sequence_of_statements of the entry_call_alternative is executed.
- Example of a timed entry call:
-- controller too busy, try something else
