In this code, you start by declaring a file pointer to standard input so that you can get interactive information from the keyboard during the spell-check process.
在这段代码中，您首先要为标准输入声明一个文件指针，以便您能够在拼写检查过程中从键盘获得交互式信息。
The iocb argument can usually be treated as an opaque cookie used by the AIO subsystem; if you need the struct file pointer for this file descriptor, however, you can find it as iocb->ki_filp.
通常可以把iocb看作AIO子系统使用的不透明数据结构。然而，如果需要文件描述符的structfile指针，可以通过iocb->ki_flip获取。
These functions must be called after the stream has been opened(obviously, since each requires a valid file pointer as its first argument) but before any other operation is performed on the stream.
这些函数必须在流打开后被调用（很明显，因为每个函数都需要一个有效的文件指针作为它的第一个参数），但是在对流有任何操作之前。
This takes three parameters: the context pointer, the path and the filename of the trust store file, and a path to a directory of certificates.
这里要用到三个参数：上下文指针、可信任库文件的路径和文件名，以及证书所在目录的路径。
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。
If this happens, hover the mouse pointer over the red circle to display the error message, make the needed correction, and save the file again.
如果出现了此情况，请将鼠标指针悬停在红色圆圈上方以显示错误消息，然后进行必要的更正并再次保存文件。
Gets the current file row pointer, stored as an object but used as an integer, from the global variable in the data area for the test engine (this will be set up later).

You can think of userdata as an array of bytes — bytes that might represent a pointer, a structure, or a file in the host application.
我们可以认为userdata就是一个字节数组——字节可以表示指针、结构或宿主应用程序中的文件。
After the fork, the parent and child have copies of all open file descriptors and data values, so the pointer works for both.
执行fork之后，父进程和子进程获得打开的所有文件描述符和数据值的拷贝，所以指针对于它们都是有效的。
The file's directory entry contains a hard link (or pointer) to the inode for the file, so every entry listed should have at least one hard link.
