[gdal-dev] How do I open vector files (e.g. shp) using GDAL

[Smart, Gary]

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"

 

I am still new to all this (having only just conquered raster formats)
so I suspect I am doing something pretty dumb.

Perhaps someone can help?
