After I added the unsafe.Pointer conversion the code compiled:
https://play.golang.org/p/QTPyhZzKZH
So my understanding is that line 15 is jut a pointer type conversion to
slice that is backed by the C array, so it doesn't matter if I choose 1 <<
20 entries or 1 << 22 entries, in both cases the

I modified my example based on the code example you gave at the bottom for
the pointer arithmetic and that compiled without any go vet errors. I
attempted to use the slice whose backing array is the C array
https://play.golang.org/p/rJoDMu5YAQ but I get a compile error:
main.go:14: cannot conve

example: https://play.golang.org/p/-cZteTY_M2
Questions:
1) Is this the best way to do pointer arithmetic in Go to process a C array
and convert it to a Go slice?
2) Go vet gives an error on line 18 but doesn't give much informa
