_VOLUME_PHYSICAL_OFFSETS structure

Description

The VOLUME_PHYSICAL_OFFSETS structure contains an array of physical offsets and accompanying physical disk numbers and is used with IOCTL_VOLUME_LOGICAL_TO_PHYSICAL to request a series of pairs of physical offsets and disk numbers that correspond to a single logical offset.

Members

`NumberOfPhysicalOffsets`

Contains the number of physical offsets returned by the call to IOCTL_VOLUME_LOGICAL_TO_PHYSICAL.

`PhysicalOffset`

Contains an array of structures of type VOLUME_PHYSICAL_OFFSET. Each element of the array contains a pair consisting of a physical disk number and an accompanying physical offset <disk number, disk offset>.
