(also known as Monitor.enter/monitor.exit) is an example of a thread synchronization structure. When lock implements exclusive access to a piece of code or resource, some synchronization tasks are clumsy or difficult to implement, such as transmitting signals to a waiting worker to start a task.The Win32 API has a rich synchronization system, which is exposed in the. NET framework with EventWaitHandle, mutexes, and semaphore classes. And some are more useful than others: for example, mutex clas

level.Details: "Threading Mess".The main mechanisms provided include: Dfake_scoped_lock, restricting a function to run on only one thread. Dfake_scoped_recursive_lock, multiple functions can nest calls on the same thread. Dfake_scoped_lock_thread_locked, at the same time, just agree that a function runs on the same thread. The containing creation and deallocation should be on the same thread. threadchecker (base/threading/thread _ch

1. Thread ConceptA process is an area of memory that contains some resources that the operating system uses to divide its work into functional units. A thread is an entity of a process, a basic unit of CPU dispatch and dispatch, and a basic unit that is smaller than the process to run independently. Threads do not own system resources themselves, but have very few resources (such as program calculators, a set of registers and stacks, etc.) that are essential for running, but share all the resour

Multithreading has been used in recent projects. I would like to take this opportunity to learn and summarize it. 1. lock and Monitor Lock is the most commonly used. The reason is that it is easy to use and the code is clean. It is implemented through Monitor internally. It acquires the exclusive lock through Monitor. Enter (obj) and releases the lock through Monitor. Exit (obj. The code in it becomes a critical section. When one thread enters, the ot

If a lock is acquired by another thread during this time, the thread can obtain a mutex lock and return FALSE if timeout (no lock is acquired within a specified period)Try_lock_until Usage Note: It accepts a point in time as a parameter, and the thread is blocked if no lock is obtained before the
