You could define a variable attribute, say "stride", that had the
value of the stride you want, but this would just be a convention.  If
you wrote a layer on top of the netCDF nc_get_vars_TYPE() call that
honored the value of this stride attribute when it existed, then I
think you would have what you want.  You would just have to make sure
code that accessed the variable used your function rather than the
library function.

Or am I misunderstanding your question?
