How to interrupt fun(a,b) in a for loop after 10 seconds?
If terminated before execution, fun x,y,z=false

for i=1:k
x,y,z=fun(a,b)
??? 10 sek > x,y,z=false,false,false
end

Thank you very much for your help, GPT doesn’t know but the matter is urgent!

You can use threads for this. Here is a simple example:

julia> function fun(a,b)
           sleep(a+b)
           return (true,true,true)
       end
fun (generic function with 1 method)

julia> task = Threads.@spawn fun(2,3)
Task (runnable) @0x000001eae0b28200

julia> sleep(10)

julia> if isnothing(task.result)
           x,y,z = (false,false,false)
       else
           x,y,z = fetch(task)
       end
(true, true, true)

julia> task = Threads.@spawn fun(6,6)
Task (runnable) @0x000001eae0b283f0

julia> sleep(10)

julia> if isnothing(task.result)
           x,y,z = (false,false,false)
       else
           x,y,z = fetch(task)
       end
(false, false, false)

It doesn't interrupt the function fun but ignores the result if it takes longer than 10sec and proceeds in the main thread.
