FILE_ALLOCATION_INFO structure (winbase.h)
Contains the total number of bytes that should be allocated for a file. This structure is used when calling the SetFileInformationByHandle function.
Syntax
typedef struct _FILE_ALLOCATION_INFO {
LARGE_INTEGER AllocationSize;
} FILE_ALLOCATION_INFO, *PFILE_ALLOCATION_INFO;
Members
AllocationSize
The new file allocation size, in bytes. This value is typically a multiple of the sector or cluster size for the underlying physical device.
Remarks
The end-of-file (EOF) position for a file must always be less than or equal to the file allocation size. If the allocation size is set to a value that is less than EOF, the EOF position is automatically adjusted to match the file allocation size.
