I understand that GDAL can open vector formats as if they were a dataset?
E.g. I read that it is possible to pass the GDALOpen either a single
.shp file (in which case it treats it as if it only had one layer) or a
directory containing multiple .shp files – which presumably it opens as
multi layered?
However, whenever I try to open vector files in this way (directory or
file) I get…
ERROR 4 - blah blah is not recognised as a supported file format”
Gary,
The GDAL library can open vector files, but it is not accomplished with
GDALOpen(). Instead you need to call OGROpen(), and use the OGR API
for vector (feature) datasets.

Good luck,
