For example, reducing unnecessary code page conversion is not goign to help if your system is heavily I/O bound due to an unfortunate table space configuration.
例如，如果由于表空间配置有问题，系统在I/O 方面存在瓶颈，那么减少不必要的代码页转换仍然无济于事。
Thus, for a typical program invocation with N options, the code needs only O(N) [N*O(1)] comparisons—an order of magnitude improvement over the legacy code.
因此，对于具有N 个选项的典型程序调用，代码只需执行O(N) [N*O(1)]比较 —这是对遗留代码的巨大改进。
This code snippet can also be modified to perform I/O of all four data transfer types.
这段代码还可以修改为进行所有四种数据传输类型的I/O。
res is the usual result of an I/O operation: the number of bytes transfered, or a negative error code.
res是IO操作的通常结果：传输的字节数，或者负值的错误码。
As described by one of its co-authors, John Goerzen, in a recent interview to o 'reilly, the book introduces Haskell with real code, real examples and tips to exploit in a business environment.
作者之一johnGoerzen近日在与oReilly的访谈中介绍，此书用现实的代码、现实的例子和技巧去介绍Haskell在业务环境中的应用。
This is why most code is compiled with -o or -o2 and specialized code being compiled at higher optimization levels.
因此，大多数代码都用—o或—o2编译，只有特殊的代码用更高的优化级别编译。
If you downloaded the code examples from the o 'reilly site, then you can follow the directions in its README files for building and running the examples in this chapter.
如果你从o' Reilly网站下载了代码例子，你可以按照README文件的指示来编译和运行这个章节的例子。
In this usage, a compiler would compile BCPL code into an intermediate machine code called O-code.
在这种用法中，编译器会将BCPL代码编译成称为o - code的中间机器代码。
This returns the following response: {" _id ": ObjectId (" 4cfa4adf528bad4e29beec9a"), "char" : "o", "code" : 111}.
这将返回以下响应：{“ _ id ”：ObjectId (“4cfa4adf 528 bad4e29 beec9a ”)，“char ”： “o ”，“code ”： 111}。
After you compile the code with GCC -g -o0 simple.c -o simple, a regular debug session might look like Listing 2.
用gcc- g - O0simple . c -o simple编译代码后，一个常规的调试会话如清单2所示。
Although BCPL was a high-level language (similar to c), the intermediate code that the compiler generated was called O-code (Object code).
尽管BCPL是一种高级语言(类似于c)，编译器生成的中间代码叫做o - code(对象代码)。
As a secondary step, the O-code was compiled into the native language of the target machine.
接下来的第二个步骤是将o -code编译成目标机器的原始语言。
First, by abstracting the O-code from the physical machine, it could easily be interpreted on a variety of hosts.
首先，通过从物理机提取o - code，可以在各个主机上轻松解译它。
The accounts wit A-code and O-code is calculated based on this value on 2099525.
使用a代码和o代码的账户基于2099525上的这个值计算。
The O-code could be interpreted on a physical machine (as a VM) or compiled from O-code to the native machine language of the host.
O-code可在物理机上解译（为VM），或从 O-code编译为主机的本机语言。
Instead, it creates a file mapping that causes the driver code and data to be fetched by paging I/O.
而是，创建一个文件映射，这个映射导致I/O内存分页读取驱动代码和数据。
What 's Big o notation on this specific code?
什么是大o符号在这个特定的代码？
As compared to '-o', this option increases both compilation time and the performance of the generated code.
与-O选项相比，这个选项会增加编辑时间和合成码的性能。
The I/O manager code 8 may use the encryption engine 10, which performs operations to encrypt and decrypt data on a coupled removable storage media 4 using one or more encryption keys.
I／O管理器代码8可使用加密引擎10，该加密引擎10执行操作以使用一个或多个加密密钥对耦合的可更换存储介质4上的数据加密和解密。
Whether to use standard O/S services, or put some code into the kernel (e. g. in a custom driver, kernel module, or VxD)
是否使用标准的操作系统服务，还是把一些代码放入内核中（如自定义驱动，内核模块。
In the language of Morse code, the letter "s" is three short dots and the letter "o" is three longer dashes.
在莫斯电码的语言中，字母s是三个短点，而字母o是三个长破折号。
But the nice O-O concepts we learn about in class aren't always so nice in practice when existing code has to be modified.
但好的面向对象的概念，我们了解在课堂上并不总是这么好的做法时，现有的代码已被修改。
The paper introduced the process of upgrading the I/O IMAGE system, the difference between different editions and the set-up of code device.
本文就I/OIMAGE系统软件升级的过程及各版本间的区别及编码器的设置做了介绍。
Code volume quite low, but when the need for greater data a longer period of time complexity is o n!
代码量挺少，不过数据较大的时候需要时间比较长，时间复杂度为O n ！
