Fear not, you'll still have access to the raw mongrel request if you want to do fancy stuff like streaming or deferred rendering outside the mutex.

不用害怕，如果您想在互斥以外做一些奇特的事情，比如流处理或延迟呈现，您仍然可以访问原始的 mongrel 请求。

可以以两种方式设置互斥的类型。

Also called a mutex.

也叫互斥信号。

But you can also create a mutex dynamically.

但是还可以动态地创建互斥对象。

After a mutex is locked, it must be unlocked.

当一个互斥锁被锁定后，它必须被解锁。

Using a mutex ensures that this doesn't happen.

使用互斥对象能够保证这种情形不会发生。

Main thread: Lock mutex and increment threadcount.

互斥我吧！

The function waits until the mutex becomes unlocked.

函数会等待互斥被解锁。

This method allows you to set mutex object attributes.

这个方法允许您设置互斥信号量对象的相关属性。

However, if the mutex is locked this call won't block.

然而，如果互斥对象已锁定，这个调用也不会阻塞。

Listing 3 illustrates a static way of setting a mutex.

清单3介绍了设置互斥的静态方法。

This creates a new mutex and initializes the structure.

这将创建一个新的互斥锁并初始化其结构。

However, a mutex should accompany each condition variable.

不过，每个条件变量都应该伴有一个互斥。

Also note that both condition variables use the same mutex.

还要注意，两个条件变量使用相同的互斥锁。

两个线程不能同时对同一个互斥对象加锁。

If Program a creates a mutex, Program B can see that same mutex.

如果程序A创建一个互斥，则程序b可以使用同一个互斥。

The mutex is simple, but there are some rules you should remember.

互斥锁很简单，但是有一些规则必须牢记。

The data structure is in effect "frozen" until the mutex is unlocked.

那个数据结构实际上是“冻结”了，直到互斥对象被解锁为止。

In either case, when control is returned, the caller holds the mutex.

无论在哪种情形中，当控制被返回时，调用者将持有互斥锁。

This way, the change to add mutex code only has to happen in one place.

这样做使增加互斥代码时只需要在一个子程序中进行改动。

If the mutex already happens to be locked, the caller will go to sleep.

如果碰巧已经锁定了互斥对象，调用者将进入睡眠状态。

The function returns when the mutex is locked, or if an error occurred.

当互斥被锁定或者发生错误时，函数返回。

The setup for a lock operation involves allocation of a prelocked mutex.
