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.
