Yield (multithreading)
From Wikipedia the free encyclopedia
In computer science, yield is an action that occurs in a computer program during multithreading, of forcing a processor to relinquish control of the current running thread, and sending it to the end of the running queue, of the same scheduling priority.
Examples
[edit]Different programming languages implement yielding in various ways.
pthread_yield()
in the language C, a low level implementation, provided by POSIX Threads[1]std::this_thread::yield()
in the language C++, introduced in C++11.- The Yield method is provided in various object-oriented programming languages with multithreading support, such as C# and Java.[2] OOP languages generally provide class abstractions for thread objects.
yield
in Kotlin
In coroutines
[edit]Coroutines are a fine-grained concurrency primitive, which may be required to yield explicitly. They may enable specifying another function to take control. Coroutines that explicitly yield allow cooperative multitasking.
