The manual (Tasks · The Julia Language) says that notify can pass val to its waiting conditions.
How can I obtain val from the woken up conditions?
That’s the value wait will return:
julia> c = Condition()
Condition(Base.InvasiveLinkedList{Task}(nothing, nothing), Base.AlwaysLockedST(1))
julia> @async println("waited for a ", wait(c))
Task (runnable) @0x00007f8ea0ebc7f0
julia> notify(c, 222); println()
waited for a 222
