std::execution::sync_wait(3)   C++ Standard Libary  std::execution::sync_wait(3)

NAME
     std::execution::sync_wait - std::execution::sync_wait

Synopsis
	Defined in header <execution>
	auto sync_wait( execution::sender auto sender )

	    requires (/*always-sends-some-values*/(sender))		  (since
     C++26)

		-> std::optional<std::tuple</*value-sent-by*/(sender)>>;

Parameters
	sender - sender upon which the completion of sync_wait is blocked

Return value
	Returns  an  optional  tuple  of  values  that were sent by the provided
     sender on its
	completion of work.

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.

See also
		       Eagerly starts a sender, returning a sender that will de-
     liver 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
	ensure_started resulting operation state is not started, the results are
     ignored. If
		       such a sender is destroyed before the  underlying  opera-
     tion completes,
		       the operation continues running detached.
		       (function template)
