The MRxCleanupFobx routine is called by RDBSS to request the network mini-redirector to close a file system object extension. RDBSS issues this call in response to receiving an IRP_MJ_CLEANUP request on a file object.

Syntax

PMRX_CALLDOWN MRxCleanupFobx;

NTSTATUS MRxCleanupFobx(
  _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

MRxCleanupFobx returns STATUS_SUCCESS on success or an appropriate NTSTATUS value, such as the following:

Return code	Description
STATUS_INTERNAL_ERROR	An internal error occurred in the network mini-redirector.

Remarks

MRxCleanupFobx is called by RDBSS as part of cleanup and close operations on a file object.

MRxCleanupFobx cannot return a value of STATUS_RETRY indicating that the call should be retried. If a retry loop is necessary, it must be handled internally in the MRxCleanupFobx routine by the network mini-redirector.
