HiveRAMInfo

  • Article

This structure contains information for use in conjunction with the IOCTL_HAL_GET_HIVE_RAM_REGION IOCTL.

typedef struct HiveRAMInfo {
  WORD wVersion;
  WORD wFlags;
  HiveRAMRegion SystemRegion;
} HiveRAMInfo;

Members

  • wVersion
    Version of this structure. Set to 1.
  • wFlags
    The required and only supported flag is HIVE_REGION_COMBINED. This means that the system and the user are in the same hive.
  • SystemRegion
    The region to use for the system hive; this is of type HiveRAMRegion.

Remarks

This structure is extensible, so you must fill in the wVersion member to prevent future incompatibility. The registry calls the IOCTL_HAL_GET_HIVE_RAM_REGION IOCTL during the first boot phase to determine whether there is a region of RAM suitable to store the data.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Pwinreg.h.
