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?
