NetAdapterCx is preview only in Windows 10, version 1903.
Calculates the number of elements contained in a range of the specified net ring buffer.
UINT32 NetRingGetRangeCount( NET_RING const *Ring, UINT32 StartIndex, UINT32 EndIndex );
The inclusive start of the range to measure.
The exclusive end of the range to measure.
The number of elements in the given range.
For example, consider a net ring containing a total of 8 elements. Index values for the elements are 0 through 7. The number of elements in the range [1, 4) is 3. This is because the EndIndex value is not included, so the range includes elements at index values 1, 2, and 3.
Similarly, the range [4, 1) includes elements at index values 4, 5, 6, 7, and 0 (looping back to the beginning of the ring), for a total of 5 elements.
Finally, note that an empty range like [2, 2) returns zero elements.
