我们真正想做的是从图像注册表获取图像描述符。
What we would really like to do is get the image descriptor from the image registry.
然后打开设备驱动器并获取文件描述符。
您可以在这里看到Cocoa的便捷性：您只需从数据表获取它的新排序描述符，使用它们来对 CPDictionary 重新排序，然后重新加载数据表。
You can see the convenience of Cocoa at work here: you simply get its new sort descriptors from the table, use them to re-sort the underlying CPDictionary, and then reload the table.
打开SCSI通用设备文件(比如sg1)获取SCSI设备的文件描述符。
Open the SCSI generic device file (such as sg1) to get the file descriptor of SCSI device.
更改mdb的部署描述符，将其配置为从WebSphereESB放置消息的队列获取消息。
Change the MDB's deployment descriptor to configure it to get messages from the queue on which WebSphere ESB puts them.
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。
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.
当实例化JAAS回调处理程序时，WebSphereApplicationServer运行时传入从部署描述符获取的用户名和密码。
The WebSphere Application Server runtime passes in a username and password that it pulls from the deployment descriptor when the JAAS callback handler is instantiated.
您的代码获取它需要的图像描述符，然后将其添加到图像注册表，并使用键为每个图像描述符建立索引。
The idea is that your code obtains the image descriptors it needs and adds them to the image registry, indexing each one with a key.
只要有可能，应尽量避免使用获取文件名的操作，而是使用获取文件描述符的操作。
Where you can, avoid the operations that take file names, and use the operations that take file descriptors instead.
这个系统调用允许你的程序从一个或多个文件描述符获取输入输出或者错误信息。
This system call allows your program to check for input, output, or error conditions on one or more file descriptors.
