[edit] Parameters
sender
-
sender upon which the completion of sync_wait is blocked
[edit] Return value
Returns an optional tuple of values that were sent by the provided sender on its completion of work.
[edit] Notes
The sender returned by sync_wait similarly to ensure_started, except that it blocks the current std::thread or thread of main until the work is completed.
[edit] See also
Eagerly starts a sender, returning a sender that will deliver the results to a receiver to which it is connected and started, if any. When the result sender is not connected to a receiver, or if the resulting operation state is not started, the results are ignored. If such a sender is destroyed before the underlying operation completes, the operation continues running detached.
