 - **OutputInformation**: A [**FS_FILTER_SECTION_SYNC_OUTPUT**](/windows-hardware/drivers/ddi/ntifs/ns-ntifs-_fs_filter_section_sync_output) structure that specifies information describing the attributes of the section that is being created.
 
+- **Flags**: Bitmask of flags providing additional information or instructions about the section.

+  | Flag | Meaning  |
+  |------|----------|
+  | FS_FILTER_SECTION_SYNC_IN_FLAG_DONT_UPDATE_LAST_ACCESS<br>0x00000001 | Specifies that the file system shouldn't update the last access time for access to the file through the section that's being created. |
+  | FS_FILTER_SECTION_SYNC_IN_FLAG_DONT_UPDATE_LAST_WRITE<br>0x00000002 | Specifies that the file system shouldn't update the last write time for modifications to the file through the section that's being created. |

+- **AllocationAttributes**: Specifies a bitmask of SEC_XXX flags that determines the allocation attributes of the section. For a description of these flags, see [**CreateFileMapping**](/windows/win32/api/winbase/nf-winbase-createfilemappinga).

 ## Remarks
 
 The [**FLT_PARAMETERS**](/windows-hardware/drivers/ddi/fltkernel/ns-fltkernel-_flt_parameters) structure for IRP_MJ_ACQUIRE_FOR_SECTION_SYNCHRONIZATION operations contains the parameters for an **AcquireForSectionSynchronization** operation represented by a callback data ([**FLT_CALLBACK_DATA**](/windows-hardware/drivers/ddi/fltkernel/ns-fltkernel-_flt_callback_data)) structure. It is contained in an FLT_IO_PARAMETER_BLOCK structure.
