Advertisements I am implementing the ‘producer-consumer problem’ in C, which solves the synchronization problem of redundant production, redundant consumption, and consuming unproduced items when multi-threading. bool expected = false; while (!atomic_compare_exchange_weak(&lock, &expected, true)) expected = false; In order to prevent duplicate access of the process, the atomic_compare_exchange_weak was used. I know that the atomic_compare_exchange_weak can… Read More How to solve producer-consumer problem using atomic_compare_exchange_weak?

Advertisements I have the following code in golang: func A(){ go print("hello") } func main() { A() // here I want to wait for the print to happen B() } How can I somehow ensure that B() will be executed only after the print has happened? >Solution : Use sync.Mutex var l sync.Mutex func A()… Read More Wait for a function to finish in golang
