Stream Interface Driver Architecture

  • Article

A stream interface driver receives commands from the Device Manager and from applications by means of file system calls. The driver encapsulates all of the information that is necessary to translate those commands into appropriate actions on the devices that it controls. All stream interface drivers, whether they manage built-in devices or installable devices, or whether they are loaded at boot time or loaded dynamically, have similar interactions with other system components. The following illustrations show the interactions between system components for a generic stream interface driver that manages a built-in device, and for a stream interface driver for a PC Card Client device.

The following illustration shows the architecture for stream interface drivers for built-in devices that are loaded by the Device Manager at boot time.
