Receiving a Wait/Wake IRP

  • Artikkeli

All PnP drivers must be prepared to receive power IRPs with minor IRP code IRP_MN_WAIT_WAKE. How a driver handles a wait/wake IRP depends on its position in the device stack, the type of device(s) it controls, and the specific states from which its device supports wake-up.

The topics in this section provide guidelines for handling this IRP based on the type of driver and its level of wait/wake support.
