MRxSetFileInfo routine

The MRxSetFileInfo routine is called by RDBSS to request that a network mini-redirector set file information on a file system object.

Syntax

PMRX_CALLDOWN MRxSetFileInfo;

NTSTATUS MRxSetFileInfo(
  _Inout_ PRX_CONTEXT RxContext
)
{ ... }

RxContext [in, out]
A pointer to the RX_CONTEXT structure. This parameter contains the IRP that is requesting the operation.

MRxSetFileInfo returns STATUS_SUCCESS on success or an appropriate NTSTATUS value, such as one of the following:

Return code	Description
STATUS_ACCESS_DENIED	The caller lacked the proper security for this operation.
STATUS_INSUFFICIENT_RESOURCES	There were insufficient resources to complete the query.
STATUS_INVALID_PARAMETER	An invalid parameter was specified.
STATUS_NETWORK_ACCESS_DENIED	Network access was denied. This error can be returned if the network mini-redirector was asked to set file information on a read-only share.
STATUS_NOT_IMPLEMENTED	A feature that is requested, such as setting file information on a remote page file, is not implemented.
STATUS_OBJECT_NAME_NOT_FOUND	The object name was not found. This error can be returned if the network mini-redirector was asked to set file information on a file, but the file doesn't exist.
STATUS_OBJECT_PATH_NOT_FOUND	The object path was not found. This error can be returned if an NTFS stream object was passed and the remote file system does not support streams.
STATUS_ONLY_IF_CONNECTED	The SRV_OPEN structure is not connected.
STATUS_REPARSE	A reparse is required to handle a symbolic link.

RDBSS issues a call to MRxSetFileInfo in response to receiving an IRP_MJ_SET_INFORMATION request.

Before calling MRxSetFileInfo, RDBSS modifies the following members in the RX_CONTEXT structure pointed to by the RxContext parameter:

The Info.FileInformationClass member is set to IrpSp->Parameters.SetFile.FileInformationClass, the specified FILE_INFORMATION_CLASS value.

The Info.Buffer member is set to Irp->AssociatedIrp.SystemBuffer.

The Info.Length member is set to IrpSp->Parameters.SetFile.Length.
