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

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.

In coroutines

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.

gollark: Anyway, if you have a design for an inscriber setup which scales better than my existing one, please do share it.
gollark: Yep.
gollark: I assume it interpreted "no items in filter slot" as "just allow anything in".
