xtd::threading Namespace Reference

Definition

The xtd::threading namespace provides classes and interfaces that enable multithreaded programming. In addition to classes for synchronizing thread activities and access to data ( xtd::threading::mutex, xtd::threading::monitor, xtd::threading::interlocked, xtd::threading::auto_reset_event, and so on), this namespace includes a xtd::threading::thread_pool class that allows you to use a pool of system-supplied threads, and a xtd::threading::timer class that executes callback methods on thread pool threads.

In addition to classes for synchronizing thread activities and access to data ( xtd::threading::mutex, xtd::threading::monitor, xtd::threading::interlocked, xtd::threading::auto_reset_event, and so on), this namespace includes a xtd::threading::jthread_pool class that allows you to use a pool of system-supplied threads, and a xtd::threading::timer class that executes callback methods on thread pool threads.

Namespaces
namespace	tasks
	The xtd::threading::tasks namespace provides types that simplify the work of writing concurrent and asynchronous code. The main types are xtd::threading::tasks::task which represents an asynchronous operation that can be waited on and cancelled, and xtd::threading::tasks::task <result_t>, which is a task that can return a value. The xtd::threading::tasks::task_factory class provides static methods for creating and starting tasks, and the xtd::threading::tasks::task_scheduler class provides the default thread scheduling infrastructure.

Classes

	The exception that is thrown when a method call is invalid for the object's current state. More...
class	thread_interrupted_exception
	The exception that is thrown when a Thread is interrupted while it is in a waiting state. More...
class	thread_local_object
	Provides thread-local storage of data. More...
class	thread_pool
	Provides a pool of threads that can be used to execute tasks, post work items, process asynchronous I/O, wait on behalf of other threads, and process timers. More...
class	thread_state_exception
	The exception that is thrown when a Thread is in an invalid ThreadState for the method call. More...
class	timeout
	Contains a constant used to specify an infinite amount of time. This class cannot be inherited. More...
class	timer
	Provides a mechanism for executing a method on a thread pool thread at specified intervals. This class cannot be inherited. More...
class	wait_handle
	Encapsulates operating system specific objects that wait for exclusive access to shared resources. More...
class	wait_handle_cannot_be_opened_exception
	The exception that is thrown when a Thread is in an invalid ThreadState for the method call. More...

Alias
using	parameterized_thread_start = delegate< void(std::any)>
	Represents the method that executes on a xtd::threading::thread.
using	thread_start = delegate< void()>
	Represents the method that executes on a xtd::threading::thread.
