int isoburn_data_source_shutdown | ( | IsoDataSource * | src, | |

) |
Disable read capabilities of a data source which was originally created by isoburn_data_source_new().
After this any attempt to read will yield a FATAL programming error event. This is usually done to allow libburn to release the drive while libisofs still holds a reference to the data source object. libisofs is not supposed to use this object for reading any more, nevertheless. The disabled state of the data source is a safety fence around this daring situation.
