_FS_FILTER_SECTION_SYNC_OUTPUT structure

Description

The FS_FILTER_SECTION_SYNC_OUTPUT structure contains information describing the attributes of the section that is being created.

Members

`StructureSize`

The size of the structure.

`SizeReturned`

The size of the structure which has been successfully populated with information on completion.

`Flags`

Specifies the support for synchronization. The following values can be used:

Name	Value
FS_FILTER_SECTION_SYNC_SUPPORTS_ASYNC_PARALLEL_IO	0x00000001
FS_FILTER_SECTION_SYNC_SUPPORTS_DIRECT_MAP_DATA	0x00000002
FS_FILTER_SECTION_SYNC_SUPPORTS_DIRECT_MAP_IMAGE	0x00000004

`DesiredReadAlignment`

Specifies the optimal size for efficient reads. Faults from the section will attempt, but not guarantee, to read in multiples of this size. This value should be a multiple of PAGE_SIZE.
