Yield (multithreading)

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.
