This section lists and describes the classes in IO<ToolKit>. Trivial classes and helper classes are not listed. The prefix os_ is used by most classes to avoid conflicts with other vendors' class names and differentiates them from ANSI/ISO classes.

Device Adapter Classes

`os_adapter`	a smart-pointer mechanism used to manage universal device adapters.
`os_buffer`	an efficient, auto-grow, memory buffer.
`os_buffer_device`	a generic interface for `os_buffer` to use with `os_adapter`.
`os_cache`	a specialized device that provides efficient, buffered I/O for all `os_adapter`-supported devices. This class can be used to improve the performance of slow or non-buffered devices. By chaining an `os_cache` into the stream, users can control the buffering policies independent of the device.
`os_cache_device`	a generic interface for `os_cache` to use with `os_adapter`.
`os_device`	a generic device interface that supports a wide variety of communication mechanisms including files, sockets, and named pipes. Designed for easy adaptation to your industry-specific devices.

Supporting Classes

`os_open_control`	manipulates values commonly used in the creation of I/O objects.
`os_io_control`	manipulates values commonly used in the creation and use of I/O objects.
`os_io_status`	obtains and manages the status of I/O objects.

`os_io_toolkit`	provides automatic initialization of IO<ToolKit>.
`os_io_toolkit_error`	represents an error condition in IO<ToolKit>.
