Member Data Documentation
◆ is_closed
| unsigned int cbmimage_dir_entry_s::is_closed |
if set to 1 (normal), this file is closed correctly. If set to 0, the file is not (yet?) closed. The CBM DOS shows such files with a "*" (i.e., "*PRG")
◆ is_locked
| unsigned int cbmimage_dir_entry_s::is_locked |
if set to 1, this file is locked. That is, it cannot be changed or deleted. The CBM DOS shows such files with a "<" (i.e., "PRG<")
◆ rel_sidesector_block
| cbmimage_blockaddress cbmimage_dir_entry_s::rel_sidesector_block |
if type is DIR_TYPE_REL, this points to the first sidesektor block on the disk. Note that in case of 1581 and other drives, this is a SUPER SIDE SECTOR BLOCK
◆ start_block
| cbmimage_blockaddress cbmimage_dir_entry_s::start_block |
the start of the file on the disk. Note that for GEOS VLIR files (is_geos_vlir is set to 1), this contains the record map, which itself points to the real starts of the streams
