Examples available for reading from RasterBand?

[jpgringo]

Hi, not an issue, but having trouble getting any guidance elsewhere on the web (probably due to the small and esoteric group who need this functionality), so apologies for that. I'm trying to read from a band consisting of float64/DOUBLE values… the Python example here is analogous to what I'm trying to accomplish. The closest equivalent, I'm guessing, to their library's ReadAsArray method is the RasterBand.ReadBlock(…) function, which I cannot get to work without causing a panic. I know the documentation is sparse (and understand why) but is there a gist or other example somewhere that might get me over that gap? Many thanks.
