You can then use the return pointer to configure other aspects of the virtual file, such as the function to call when a read is performed on the file.
然后就可以使用这个返回的指针来配置这个虚拟文件的其他参数，例如在对该文件执行读操作时应该调用的函数。
First, the Vee-Table pointer is used to access virtual functions, and data members are accessed directly using compile time offsets.
首先，Vee -Table指针用于访问虚函数，而对数据成员的访问直接使用编译时偏移量实现。
Increments the row pointer for the next virtual user or, if the end of the file is reached, go back to the beginning of the file and reset the pointer to 1.
为下一位虚拟用户增加行指针或者，如果已经到达文件的末尾，就回到这个文件的起始，使指针重新回到1。
The virtual memory area (VMA) pointer needs to be added in as the first parameter followed by the usual four parameters (start, end, size, and protection flags).
虚拟内存区域（VMA）指针要作为第一个参数，然后是四个常用的参数（start，end，size和protection标记）。
Every object has some additional bytes that the common language runtime USES to manage the object, such as the object's virtual table pointer and a reference to a sync block.
每个对象都有一些附加字节，通用语言运行库用来管理对象，如对象的虚表指针和同步锁定引用。
If the function is virtual and the call is through a reference or pointer, then the compiler generates code to determine which version to run based on the dynamic type of the object.
如果函数是虚函数，并且调用是通过引用或者指针，编译器基于动态类型生成代码确定调用哪个版本。
Each CUDA context has it's own virtual memory space, therefore you can not use a pointer from one context inside an another context.
每个CUDA上下文都有它自己的虚拟内存空间，因此你不能使用一个指针从一个上下文在另一个上下文。
After that happens, even when you have a pointer to base, calling a virtual method can call a derived method.
发生后，即使你有一个指针基地，调用virtual方法可以调用派生的方法。
