The FS_FILTER_SECTION_SYNC_OUTPUT structure contains information describing the attributes of the section that is being created.
Syntax
typedef struct _FS_FILTER_SECTION_SYNC_OUTPUT {
ULONG StructureSize;
ULONG SizeReturned;
ULONG Flags;
ULONG DesiredReadAlignment;
} FS_FILTER_SECTION_SYNC_OUTPUT, *PFS_FILTER_SECTION_SYNC_OUTPUT;
Members
StructureSize
The size of the structure.
SizeReturned
The size of the structure which has been successfully populated with information on completion.
