Power Management Implementation in Stream Interface Drivers (Windows Embedded CE 6.0)

1/6/2010

Before your driver can support power management, it must expose the stream interface. Exposing the stream interface provides a set of entry points to implement the standard file I/O functions that are used by the kernel.

In addition to the stream interface functions, your driver must support the IOCTL_POWER_CAPABILITIES and IOCTL_POWER_SET I/O controls.

For more information about support for IOCTL_POWER_SET, see IOCTL_POWER_SET Request Processing.

For more information about support for IOCTL_POWER_CAPABILITIES, see Device Power Capabilities.

Once you have configured the stream interface, you can configure your driver to support power management. For more information, see Power Management Implementation in Drivers.
