[gdal-dev] How to delete shapefile

[Clay, Bruce]

I am trying to delete a temporary shapefile after running a process with
the following code.

 

int GdalWrapper::DeleteDataset(const char *datasetName)

{

      int status = -1;

 

      if (datasetName != NULL)

      {

            OGRDataSource *dataSrc = OpenDatasetFile(datasetName);

            if (dataSrc != NULL)

            {

                  try

                  {

                        int refCnt = dataSrc->GetSummaryRefCount();

                        if (refCnt > 0)

                        {

                              dataSrc->Release();

                        }

                        int deleteOk =
dataSrc->TestCapability(ODsCDeleteLayer);

                        if (deleteOk == TRUE)

                        {

                              dataSrc->DeleteLayer(0);

                              status = 0;

                        }

                        else

                        {

                              mLastErrorMsg = "Can not delete requested
dataset";

                        }

                  }

                  catch(...)

                  {

                        mLastErrorMsg = "Could not delete layer: ";

                        mLastErrorMsg += datasetName;

                  }

 

            }

 

      }

 

      return(status);

}

 

The TestCapability always returns FALSE.  If I call DeleteLayer anyway I
get an unsupported operation error messege.

I am using GDAL 1.5.3 with Visual Studio 2005.

 

Is there an error in my code or a different way to delete a shapefile
using GDAL or do I have to go to the operating system and find all of
the files that make up the shapefile and delete them that way?
