RxpReferenceNetFcb function

-description

RxpReferenceNetFcb increments the reference count on an FCB.

-parameters

-param Fcb

A pointer to the FCB structure to be referenced.

-returns

RxpReferenceNetFcb returns the final reference count after the reference.

-remarks

A number of debugging macros are defined in fcb.h that are the preferred way to call this routine. These macros provide a wrapper around the RxpReferenceNetFcb or RxpDereferenceNetFcb routines used for file structure management operations on FCB structures. The RxReferenceNetFcb macro is the preferred way to call this routine. This macro first calls the RxpTrackReference routine to log diagnostic information about the request before calling the RxpReferenceNetFcb routine.

On checked builds, RxpReferenceNetFcb causes the system to ASSERT if the node type for the structure is not an FCB.
