1、If Program a creates a mutex, Program B can see that same mutex.
2、Also called a mutex.
3、Why mutex at all?
4、The mutex API provides five functions: three are used for locking, one for unlocking, and another for testing a mutex.
5、Only one task may hold the mutex at a time, and only this task can unlock the mutex.
6、When publishing its data, it would acquire a mutex, do writes to the bus, and release the mutex.
7、有一些POSIX服務可用於鎖定pthread _ mutex和為pthread _ mutex解鎖。
8、The problem with a mutex-based approach.
9、Main thread: Lock mutex and increment threadcount.
10、However with a PCP mutex, both the ADC and DAC mutex will have a ceiling priority equal to the SI's task priority.
11、Using a mutex ensures that this doesn't happen.
12、This method allows you to set mutex object attributes.
13、With the priority ceiling Protocol (PCP) method each mutex has a defined priority ceiling, set to that of the highest priority task which USES the mutex.
14、After a mutex is locked, it must be unlocked.
15、All threads that go to sleep from calling pthread_mutex_lock on an already-locked mutex will "queue up" for access to that mutex.
16、HHandle is the pointer to the mutex handle.
17、Listing 3 illustrates a static way of setting a mutex.
18、The function returns when the mutex is locked, or if an error occurred.
19、In either case, when control is returned, the caller holds the mutex.
20、When invoked, pthread_cond_wait unlocks the mutex and then pauses execution of its thread.
21、Its effective usage can achieve multithread synchronization and mutex to ensure program running correctly.
22、The theory of displaying bitmap and the method of creating mutex are also expounded.
23、Based on priority inheritance protocol, a muti thread mutex algorithm is presented, which can prevent deadlock and priority inversion.
24、A thread holding a mutex can be de-scheduled, perhaps because it was the end of its time-slice.
25、After locking that, it creates a new thread and increments threadcount; after it's done, it unlocks the mutex.
26、You should always unlock a mutex that you've locked as soon as safely possible (to increase performance).
27、When the original file handle is closed, the mutex handle is closed and the protections against data corruption are lost.
28、ReleaseMutex is called when the owning thread no longer needs the mutex, and it can be conveniently released to the system.
29、Because you're sharing the same mutex for push and pop operations, the data-read speed is somewhat compromised as writer threads access the lock.
30、This routine is called twice-before and after mutex acquisition-to determine whether further processing is required based on the time elapsed.
31、這個例程做了一些新的工作；它鎖定一個叫做count _ mutex的互斥量。
32、Most programmers know that the synchronized keyword enforces a mutex (mutual exclusion) that prevents more than one thread at a time from entering a synchronized block protected by a given monitor.
33、緩衝區的獲取是通過使用鎖存器（latch）和鎖訪問資訊來管理的，該鎖存器稱作 mutex。
34、如果執行緒1要執行，它就要鎖定rand _ mutex，可是這個互斥量已經被執行緒2阻塞了。
35、如果執行緒2要執行，它就要鎖定count _ mutex，而這個互斥量已經被執行緒1佔有了。
36、In VAX/VMS, a semaphore that is used to control exclusive access to a region of code that can share a data structure or other resource. The mutex (mutual exclusion) semaphore ensures that only one process at a time has access to the region of code.
37、另外一些可選的原始同步物件就是Monitor或mutex去確保所有將來的事件被排隊直到當前的事件處理函式執行完成。
