FSCTL_SET_PERSISTENT_VOLUME_STATE control code

  • Article

The FSCTL_SET_PERSISTENT_VOLUME_STATE control code sets persistent settings for a file system volume. Persistent settings remain on a file system volume between reboots of the computer.

To perform this operation, call FltFsControlFile or ZwFsControlFile with the following parameters.

Parameters

  • FileObject [in]: FltFsControlFile only. A file object pointer for the file system volume. This parameter is required and cannot be NULL.

  • FileHandle [in]: ZwFsControlFile only. A file handle for the file system volume. This parameter is required and cannot be NULL.

  • FsControlCode [in]: The control code for the operation. Use FSCTL_SET_PERSISTENT_VOLUME_STATE for this operation.

  • InputBuffer [in]: A pointer to a caller-allocated FILE_FS_PERSISTENT_VOLUME_INFORMATION structure that contains the persistent settings for a file system volume.

  • InputBufferLength [in]: The size, in bytes, of the buffer pointed to by the InputBuffer parameter.

  • OutputBuffer [out]: Not used with this operation; set to NULL.

  • OutputBufferLength [out]: Not used with this operation; set to zero.

Status block

FltFsControlFile or ZwFsControlFile returns STATUS_SUCCESS or an appropriate NTSTATUS value such as one of the following:

Code Meaning
STATUS_NOT_SUPPORTED The requested registry setting is not per volume, or the caller specified an incorrect version number in the Version member of FILE_FS_PERSISTENT_VOLUME_INFORMATION.
STATUS_INVALID_PARAMETER The file system volume is not an open user volume, or the caller specified an invalid flag in the FlagMask member of FILE_FS_PERSISTENT_VOLUME_INFORMATION.
STATUS_BUFFER_TOO_SMALL The buffer that the InputBuffer parameter points to is not large enough to hold the persistent-settings data. In this case, no persistent-settings data is set. This is an error code.
STATUS_ACCESS_DENIED The caller cannot access the file system volume.
STATUS_VOLUME_DISMOUNTED The file system volume is dismounted.
STATUS_TOO_LATE The file system volume is shut down.
STATUS_MEDIA_WRITE_PROTECTED The file system volume is read only.
