How to wait for async method to complete?
Avoid async void. Have your methods return Task instead of void. Then you can await them.
How does await work in an asynchronous program?
They have a thread pool SynchronizationContext instead of a one-chunk-at-a-time SynchronizationContext, so when the await completes, it schedules the remainder of the async method on a thread pool thread. The method is able to complete, which completes its returned task, and there’s no deadlock.
Which is the best way to create a task in async?
The first problem is task creation. Obviously, an async method can create a task, and that’s the easiest option. If you need to run code on the thread pool, use Task.Run. If you want to create a task wrapper for an existing asynchronous operation or event, use TaskCompletionSource .
What are the different types of async methods?
There are three possible return types for async methods: Task, Task and void, but the natural return types for async methods are just Task and Task .
How to wait in Bash for several subprocess to finish?
How to wait in a bash script for several subprocesses spawned from that script to finish and return exit code !=0 when any of the subprocesses ends with code !=0 ? The above script will wait for all 10 spawned subprocesses, but it will always give exit status 0 (see help wait ).
How to wait for multiple processes to finish?
Example, wait for all three processes to finish, log a warning if execution takes loger than 5 seconds, stop all processes if execution takes longer than 120 seconds. Don’t exit program on failures.
Why does my shell not send a SIGHUP?
One of the results is that the shell won’t send it a SIGHUP (If the shell receives a SIGHUP, it also sends a SIGHUP to the process, which normally causes the process to terminate). And obviously, it can only be applied to background jobs (because you cannot enter it when a foreground job is running).
