Detailed Description

ISO-9660 Supplementary Volume Descriptor.

This is used for Joliet Extensions and is almost the same as the the primary descriptor but two unused fields, "unused1" and "unused3 become "flags and "escape_sequences" respectively.

Field Documentation

◆ abstract_file_id

dchar_t iso9660_svd_s::abstract_file_id[37]
