FILE_SEGMENT_ELEMENT union
Applies to: desktop apps only
Union that contains a 64-bit value that points to a page of data. This is used by the ReadFileScatter and WriteFileGather functions.
Syntax
typedef union _FILE_SEGMENT_ELEMENT {
PVOID64 Buffer;
ULONGLONG Alignment;
} FILE_SEGMENT_ELEMENT, *PFILE_SEGMENT_ELEMENT;
Members
- Buffer
-
PVOID64 representation of 64-bit value.
Assigning a pointer to the Buffer member will sign-extend the value if the code is compiled as 32-bits; this can break 32-bit large-address aware applications running on systems configured with 4-Gigabyte Tuning or running under WOW64 on 64-bit Windows. Therefore, use the PtrToPtr64 macro when assigning pointers to the Buffer member.
- Alignment
-
ULONGLONG representation of 64-bit value.
