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 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. |
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.
