View the official Windows hardware development documentationNo description available.
The FSCTL_INVALIDATE_VOLUMES control code finds and removes all the volumes mounted on the device represented by the specified file object or handle.
To perform this operation, minifilter drivers call FltFsControlFile, and file systems, redirectors, and legacy file system filter drivers call ZwFsControlFile, using the following parameters.
FileObject [in]: Handle to the device. To obtain a device handle, call the CreateFile function.
FileHandle [in]: Handle to the device. To obtain a device handle, call the CreateFile function.
FsControlCode [in]: Control code for the operation. Use FSCTL_INVALIDATE_VOLUMES for this operation.
InputBuffer [in]: Not used with this operation; set to NULL.
InputBufferLength [in]: Not used with this operation; set to zero.
OutputBuffer [out]: Not used with this operation; set to NULL.
OutputBufferLength [out]: Not used with this operation; set to zero.
FltFsControlFile and ZwFsControlFile return STATUS_SUCCESS if the operation succeeds or an appropriate NTSTATUS value.
FSCTL_INVALIDATE_VOLUMES is sent to the file system's control (that is, named) device object, not to a volume device object. For more information about Control Device Objects, see Creating the Control Device Object.
FAT and NTFS file systems handle surprise removal by responding to IRP_MJ_PNP/IRP_MN_SURPRISE_REMOVAL.
