A minifilter driver can register a routine of type PFLT_GET_OPERATION_STATUS_CALLBACK as the minifilter driver's OperationStatusCallback routine.
Syntax
PFLT_GET_OPERATION_STATUS_CALLBACK PfltGetOperationStatusCallback;
void PfltGetOperationStatusCallback(
[in] PCFLT_RELATED_OBJECTS FltObjects,
[in] PFLT_IO_PARAMETER_BLOCK IopbSnapshot,
[in] NTSTATUS OperationStatus,
[in, optional] PVOID RequesterContext
)
{...}
Parameters
[in] FltObjects
A pointer to an FLT_RELATED_OBJECTS structure that contains opaque pointers for the objects related to the current operation.
[in] IopbSnapshot
A pointer to the data structure containing parameters from the IO Request Packet for the operation.
[in] OperationStatus

Remarks
A minifilter driver can register a routine of type PFLT_GET_OPERATION_STATUS_CALLBACK as the minifilter driver's OperationStatusCallback routine.
Most minifilter drivers never need to register a routine of type PFLT_GET_OPERATION_STATUS_CALLBACK. Normally, a minifilter driver only calls this routine to determine whether a requested opportunistic lock was granted.
