RxIndicateChangeOfBufferingState function (rxprocs.h)
RxIndicateChangeOfBufferingState is called to register a change buffering state request (an oplock break indication, for example) for later processing. If necessary, worker thread routines for further processing are activated.
Syntax
void RxIndicateChangeOfBufferingState(
PMRX_SRV_CALL SrvCall,
PVOID SrvOpenKey,
PVOID Context
);
Parameters
SrvCall
A pointer to the SRV_CALL structure.
SrvOpenKey
A pointer to the key for the SRV_OPEN structure.
Context
A pointer to the context to be passed back to the network mini-redirector during callbacks for processing the request.
Return value
None
Remarks
RxIndicateChangeOfBufferingState registers the change buffering state request by either inserting it in the registration list (DPC Level processing ) or the appropriate dispatcher/handler list.
This is an instance in which the buffering state change request from the server identifies the SRV_OPEN structure using the key generated by the server. This implies that the key needs to be mapped onto the SRV_OPEN structure locally.
The internal routines called by this routine can fail because of a lack of available memory (unable to allocate non-paged pool memory, for example), but since this is a VOID routine no error is returned when this condition occurs.
If a buffering state request can be processed immediately instead of being queued for processing later, then RxChangeBufferingState can be called.
