Function Documentation

fast_delete_and_close()

void gdal::fast_delete_and_close	(	gdal::dataset_unique_ptr &	dataset,
		GDALDriverH	driver,
		const QString &	path
	)

Performs a fast close of an unwanted GDAL dataset handle by deleting the underlying data store.

Use when the resultant dataset is no longer required, e.g. as a result of user cancellation of an operation.

Requires a gdal dataset pointer, the corresponding gdal driver and underlying dataset file path.
