When used along with the Mutex, pthreads conditional variables provide event-based synchronization between threads, but they are synchronous.

当与互斥一起使用时，pthreads条件变量可以在线程之间提供基于事件的同步机制，不过这是同步的。

Otherwise, you can use the "recursive" mutex type, which allows the holder of the lock to lock the same mutex multiple times.

另外，您还可以使用“递归”类型的互斥量，这种互斥量允许对同一个互斥量锁定多次。

to "lock" a mutex means to wait until the mutex is unowned, and then make it owned by the current thread.

锁定“一个互斥体意味着等待，直至该互斥体变为无主，然后令其被当前线程拥有。”

Unlocking the mutex happens immediately, but waiting on the condition mycond is normally a blocking operation, meaning that our thread will go to sleep, consuming no CPU cycles until it is woken up.

对互斥对象解锁会立即发生，但等待条件mycond通常是一个阻塞操作，这意味着线程将睡眠，在它苏醒之前不会消耗CPU周期。

A signal's mutex is automatically locked whenever any of the signal's methods are called.

调用信号的任何方法时,信号的互斥体都会自动加锁.

Without the mutex, thread_function() will overwrite the incremented value when it wakes up if our main thread increments myglobal during thread_function()'s one-second nap.

不使用互斥对象时，即使主线程在thread function（）线程睡眠一秒钟期间内对myglobal加一，thread function（）苏醒后也会覆盖主线程所加的值。

Mutexes will insert a" memory barrier," which ensures that the writes to main memory occur in the order the threads lock the mutex.

互斥对象将插入一道“内存关卡”，由它来确保对主存的写入按照线程锁定互斥对象的顺序进行。

each mutex is always either owned or unowned.

Before it is put into the thread lock cache, the mutex is prelocked by the thread.

It also allows you to unlock the mutex and wait on the condition variable atomically, without the possible intervention of another thread.

它还允许您原子地（atomically）解除互斥的锁定，并等待条件变量，而不会有干涉其他线程的可能。

Next it releases the signal's mutex, before invoking the combiner to iterate through the slot list.

接着,它会在调用合并器遍历插槽链表之前,释放信号的互斥体.
