RxReleaseFcbResourceInMRx function (mrxfcb.h)
RxReleaseFcbResourceInMRx releases the FCB resource acquired by a network mini-redirector driver.
Syntax
void RxReleaseFcbResourceInMRx(
PMRX_FCB Fcb
);
Parameters
Fcb
A pointer to the FCB. This parameter is required and cannot be NULL.
Return value
None
Remarks
The synchronization resources of interest to a network mini-redirector driver are primarily associated with the FCB. There is a paging I/O resource and a regular resource. The paging I/O resource is managed internally by RDBSS. The only resource accessible to a network mini-redirector driver is the regular resource.
The RxReleaseFcbResourceInMRx routine will release an FCB resource previously acquired by calling RxAcquireExclusiveFcbResourceInMRx, RxAcquireSharedFcbResourceInMRx, or RxAcquireSharedFcbResourceInMRxEx. If there are any pending buffering state change requests for this FCB, then these buffering state changes will be processed first before the RxReleaseFcbResourceInMRx routine returns.
