FILE_ALLOCATED_RANGE_BUFFER structure (winioctl.h)
Indicates a range of bytes in a file. This structure is used with the FSCTL_QUERY_ALLOCATED_RANGES control code. On input, the structure indicates the range of the file to search. On output, the operation retrieves an array of FILE_ALLOCATED_RANGE_BUFFER structures to indicate the allocated ranges within the search range.
Syntax
