MRxSetQuotaInfo routine
TheMRxSetQuotaInfo routine is called by RDBSS to request that a network mini-redirector set quota information on a file system object.
Syntax
PMRX_CALLDOWN MRxSetQuotaInfo;
NTSTATUS MRxSetQuotaInfo(
_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
MRxSetQuotaInfo 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_CONNECTION_DISCONNECTED | The connection was disconnected. |
| STATUS_INSUFFICIENT_RESOURCES | There were insufficient resources to complete the query. |
| STATUS_INVALID_PARAMETER | An invalid parameter was specified. |
| STATUS_NOT_SUPPORTED | Quotas are not supported. |
Remarks
RDBSS issues a call to MRxSetQuotaInfo in response to receiving an IRP_MJ_SET_QUOTA request.
Before calling MRxSetQuotaInfo, RDBSS modifies the following members in the RX_CONTEXT structure pointed to by the RxContext parameter:
The Info.Buffer member is set to the user buffer from I/O request packet. This buffer has already been locked by RDBSS if needed.
The Info.LengthRemaining member is set to IrpSp->Parameters.SetQuota.Length.
