Spawn a new thread of execution.
template< typename ExecutionContext, typename F, typename CompletionToken = DEFAULT> DEDUCED co_spawn( ExecutionContext & ctx, F && f, CompletionToken && token = DEFAULT, typename enable_if< is_convertible< ExecutionContext &, execution_context & >::value >::type * = 0);
The entry point function object f
must have the signature:
awaitable<void, E> f();
where E
is convertible from ExecutionContext::executor_type
.
