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
)
{ ... }

Parameters

RxContext [in, out]

A pointer to the RX_CONTEXT structure. This parameter contains the IRP that is requesting the operation.

Return value

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

Return codeDescription
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.

 

Remarks

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.
