waitHandles

WaitHandles are synchronization primitives used in concurrent programming to manage the execution of threads. They are a fundamental concept in multithreading, providing a way to coordinate the activities of multiple threads and manage access to shared resources. WaitHandles are typically used to signal the occurrence of an event or to indicate that a particular condition has been met.

There are several types of WaitHandles, including ManualResetEvent, AutoResetEvent, Mutex, and Semaphore. Each type serves a specific purpose in thread synchronization:

ManualResetEvent allows multiple waiting threads to proceed when the event is set. It remains in the signaled state until it is manually reset.

AutoResetEvent automatically resets to the nonsignaled state after releasing a single waiting thread, ensuring that only one thread proceeds at a time.

Mutex provides mutual exclusion, allowing only one thread to enter a critical section at a time. It is useful for protecting shared resources from concurrent access.

Semaphore controls access to a resource pool, allowing a specified number of threads to enter a critical section simultaneously.

WaitHandles are essential for building robust and efficient multithreaded applications. They help prevent race conditions, deadlocks, and other synchronization issues by ensuring that threads operate in a coordinated manner. Proper use of WaitHandles can significantly improve the performance and reliability of concurrent programs.
