Writing

bk_write_image()

Writes the ISO to newImagePathAndName.

If you don't care about the creationTime recorded on the new ISO (this is different from the creation time of the ISO file as recorded by the normal filesystem) just use time(NULL) for the parameter, so the current time will be stored as the creation time on the new ISO.

The filenameTypes parameter is different from the one used when reading the directory tree (it doesn't have to be the same). This one tells bk which filename types will be used on the new image. It is recommended that you use all of them: FNTYPE_9660 | FNTYPE_ROCKRIDGE | FNTYPE_JOLIET. Notice that to specify more than one type you | them together.

progressFunction is a pointer to a function that takes a VolInfo* and a double as parameters and returns void. bk will call this function every 1 second or so and the double will have a number between 0 and 100, which is a good approximation of how much has been written already. You can pass in NULL if you like but in that case control won't be returned to your code until bk_write_image() is finished doing what it has to do so you can't update a progress bar or cancel writing.
