IDE_POWER_INFO structure (irb.h)

  • Article

The POWER_CHANGE_INFO structure is used in conjunction with the IDE_REQUEST_BLOCK to request a power state change.

Note  The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
