[gdal-dev] Question about command line options -append

[Victor Chernetsky]

Thanks, this worked!

I have a followup question: how does gdal/ogr2ogr knows that my destination
dataset/layer exists?
For instance, -append option suppose to do different things if layer
exists, or not. I don't see any isExists() APIs that would check it.

Thanks,
*Victor Chernetsky*
