Critical section
|
|
In computer programming a critical section is a piece of code that can only be executed by one process at a time. It will usually terminate in fixed time and a process will only have to wait a fixed time to enter it. Some synchronisation mechanism is required at the entry and exit of the critical section to ensure exclusive use, for example a semaphore.Template:Compu-stub
