这个参数的写法是ptr:domain.

第一步：登录PTR客户端并创建一个1级角色。

If(auto spt= wp. lock()){// to be safe, have to be copy into a shared_ptr before usage.
If(autospt=gw.lock()){//使用之前必须复制到shared_ptr.

If ptr is NULL, the behavior is the same as calling std::malloc(new_size).
若ptr是NULL，则行为与调用malloc(new_size)相同。

The referenced object shall remain valid at least as long as there is an exception_ptr object that refers to it….
被引用对象保持合法，只要至少要有一个exception_ptr对象引用它。

If ptr is specified as NULL, then realloc() is equivalent to calling malloc(size).
如果ptr为NULL，则行为等价于malloc(size)。

You can see here that the RString structure contains two values: ptr and len, but not the actual string data itself.
如你所见RString结构包含了两个值：ptr和len，但并不包含字符串本身的数据。

Arpa zone typically have PTR records containing a domain name corresponding to the IPv4 address in question.

Brainfuck programs can be transliterated into C using the following substitutions, assuming ptr is of type char*:.
Brainfuck程序可以用下面的替换方法翻译成C语言（假设ptr是char*类型）：.

PTR records are primarily used for reverse name resolution, as they point IP addresses back to a particular name.
PTR记录主要用于逆向名称解析，因为它们将IP地址反向指回到具体名称。

This RString structure contains a character array called ary and not the ptr, len and shared values we saw above.
这个RString结构体包含了一个字符数组ary但没有ptr，len和shared值，就像上图中我们看到的。

Unsafe_convert(Ptr{T}, A) is provided, the memory layout must correspond in the same way to these strides.
Unsafe_convert(Ptr{T},A)，则内存布局必须以与这些间隔相同的方式对应。

Obviously, any other globals in your module that depends on foo_data_ptr would also have to be initialized in__init__.
显然，你的模块（Module）中，任何其他依赖于foo_data_ptr的全局量也必须在__init__中被初始化。

The PTR is another[example] of corruption, and we will come out of this crisis with measures that we have announced from this Parliament.
PTR是另一种腐败的例子，我们将在这次危机中实施我们在议会上宣布的措施。

If a function captures ownership of an object created in the heap, make the argument type shared_ptr or unique_ptr.
如果函数中传递堆中创建的对象，则使参数类型为shared_ptr或者unique_ptr.

Through the ret_ptr, the program can easily calculate the value of real_ptr and then pass real_ptr to release the memory.
通过ret_ptr，程序可以很容易的算出real_ptr的值，然后将real_ptr传给free释放内存。

Idris defines several primitive types: Int, Integer and Double for numeric operations, Char and String for text manipulation, and Ptr which represents foreign pointers.
Idris定义了一些原语（Primitive）类型：Int、Integer和Double用于数值类型，Char和String用于文本操作，Ptr则表示外部指针。

A weak_ptr provides access to an object that is owned by one or more shared_ptr instances, but does not participate in reference counting.
Weak_ptr提供对一个或多个shared_ptr实例拥有的对象的访问，但不参与引用计数。

In the code below, I show use of TR1:: shared_ptr, because its more intuitive behavior when copied generally makes it preferable to auto_ptr.
在下面的代码中，我展示了tr1::shared_ptr的使用，因为当进行通常的拷贝时它的更符合直觉的行为使得它比auto_ptr更可取。

If ptr points to a character whose address is 1000, then above operation will point to the location 1001 because next character will be available at 1001.
如果ptr指向一个地址为1000的字符，上面的运算会导致指针指向位置1001，因为下一个字符位置是在1001。

Note also that the use of an object(the TR1:: shared_ptr) to manage a resource(the dynamically allocated Image) has again pared the length of changeBackground.
同样请注意一个管理资源（动态分配的Image）的对象（tr1::shared_ptr）的使用再次缩短了changeBackground的长度。

In C++11, std::auto_ptr<T> has been replaced by std::unique_ptr<T> which takes advantage of rvalue references.
在C++11中，std::auto_ptr<T>已被取代std::unique_ptr<T>它利用了右值参考。
