This question already has an answer here: TPL wait for task to complete with a specific return value 2 answers There are three tasks that I wish to run in parallel.

What is the difference between wait(null) and wait(&status) in c system programming? And what is the content of the pointer status ? user43968 If you call wait(NULL) ( wait(2) ), you only wait for any child to terminate.
