Namely only allow at any time a thread that sharing data resources is conducted interviews.If there are a plurality of threads to attempt to access simultaneously the critical section, so after having a thread to enter, other all attempt to access this critical section thread will be suspended, and be continued until that the thread that enters the critical section leaves.Only after the critical section was released, other thread just can continue to seize, and reaches the purpose of multithreading shared resource with this.
(2) mutex: design for coordinating common independent access to a shared resource
Mutex is very similar to the critical section, and the thread that only has Mutex object just has the authority of access resources, because Mutex object only has one, has just determined that therefore under any circumstance this shared resource can not accessed by a plurality of thread simultaneously.The current thread that occupies resource should be surrendered the Mutex object authority that has after task is handled, so that other thread is able to access resources after acquisition.
Mutex is more complicated than the critical section.Because use mutual exclusion not only can realize in the same application different threads that the safety of resource is shared, and can realize the safety of resource is shared between the thread of different application.
(3) semaphore: have the limited quantity user resources and design for controlling
Different from the front several method, this method allows a plurality of threads in the same resource of synchronization access, but need to be limited in the thread maximum number that synchronization is accessed this resource by semaphore.
(4) event: be used for notifying thread to have some events to occur, thereby start the beginning of subsequent tasks
Event object also can keep by the mode that notice operates the synchronous of thread, and can realize the thread synchronization operation in different processes.
Utilize above these several modes to realize the synchronous and mutual exclusion of thread, can guarantee the safety of thread, but the complicacy that the system that also increases simultaneously processes, and to a certain extent can reduction the efficient of system's operation.
