NetRingAdvanceIndex function (ring.h)
The NetRingAdvanceIndex function advances the index in a net ring forward, wrapping around if necessary.
Syntax
UINT32 NetRingAdvanceIndex(
[_In_] NET_RING const *Ring,
[_In_] UINT32 Index,
[_In_] INT32 Distance
);
Parameters
[_In_] Ring
A pointer to a NET_RING to access.
[_In_] Index
The index value to advance.
[_In_] Distance
The distance to advance the index.
Return value
