  • The most fundamental point to understand about the C++ I/O system is that it operates on streams. A stream is an abstraction that either produces or consumes information. A stream is linked to a physical device by the C++ I/O system. All streams behave in the same manner, even if the actual physical devices they are linked to differ. Because all streams act the same, the same I/O functions and operators can operate on virtually any type of device. For example, the same method that you use to write to the screen can be used to write to a disk...

  • The role of the operating system in computer I/O is to manage and control I/O operations and I/O devices. Although related topics appear in other chapters, here we bring together the pieces to paint a complete picture of I/O. First, we describe the basics of I/O hardware. Next, we discuss the I/O services provided by the operating system and the embodiment of these services in the application I/O interface. Then, we explain how the operating system bridges the gap between the hardware interface and the application interface.

  • Since the beginning of this book you have been using the C++ I/O system, but you have been doing so without much formal explanation. Since the I/O system is based upon a hierarchy of classes, it was not possible to present its theory and details without first discussing classes and inheritance. Now it is time to examine the C++ I/O system in detail. The C++ I/O system is quite large, and it won’t be possible to discuss here every class, function, or feature, but this module will introduce you to the most important and commonly used parts. Specifically, it shows...

  • The problem with programmed I/O is that the processor has to wait a long time for the I/ O module of concern to be ready for either reception or transmission of data. The processor, while waiting, must repeatedly interrogate the status of the I/O module. As e result, the level of the performance of the entire system is severely degraded.
