STORAGE_DEVICE_POWER_CAP structure (ntddstor.h)
This structure is used as an input and output buffer for the IOCTL_STORAGE_DEVICE_POWER_CAP.
Syntax
typedef struct _STORAGE_DEVICE_POWER_CAP {
ULONG Version;
ULONG Size;
STORAGE_DEVICE_POWER_CAP_UNITS Units;
ULONGLONG MaxPower;
} STORAGE_DEVICE_POWER_CAP, *PSTORAGE_DEVICE_POWER_CAP;
Members
Version
The version of this structure. This should be set to STORAGE_DEVICE_POWER_CAP_VERSION_V1.
Size
The size of this structure, in bytes.
Units
The units of the MaxPower value. This value can be either a percentage (0-100%) or an absolute value in milliwatts. The output buffer's Units value will match the value from the input buffer.
MaxPower
On input, MaxPower specifies the desired maximum power consumption value for the storage device. On output, MaxPower contains the value of the actual maximum power consumption level of the device. The output buffer value may be equal to, less than, or greater than the desired threshold, depending on what the device supports.
