  • Article

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.
