If input and output drive are the same, then isoburn_prepare_disc() is to

be used. It will lead to an add-on session on appendable or overwriteable

Modifying:

or overwriteable without a valid ISO image. To prepare for such an image

|
|

|
generation run, use isoburn_prepare_new_image(). The run will copy file data

from an eventual input drive with valid image, add any newly introduced data

from the local filesystem, and produce a first session on output media.

If the output drive is not the input drive, and if it bears blank media
|
|
|
|
|
or overwriteable without a valid ISO image, then one may produce a consolidated

image with old and new data. This will copy file data from an eventual input
|

drive with valid image, add any newly introduced data from the local

filesystem, and produce a first session on output media.
