Detailed Description
Image specific settings for all types of images .
this type contains data that is specific to each image type, but that is needed from all types.
This type is subject to change and not part of the API.
Member Data Documentation
◆ dir_tracks
| uint8_t cbmimage_image_settings_s::dir_tracks[2] |
the track(s) where the directory is located. If there is only 1 track, the other must be 0.
The tracks must be numerically sorted, filling the remaining entries with a 0.
◆ has_super_sidesector
| int cbmimage_image_settings_s::has_super_sidesector |
0 if side-sector blocks are normal side-sector blocks
1 if there is a super side-sector block instead (i.e. 1581)
◆ info
| cbmimage_blockaccessor* cbmimage_image_settings_s::info |
accessor for the info block.
On some images (e.g., D64, D71 and D40), this is identical to the BAM block.
On others, it is not.
◆ is_partition_table
| unsigned int cbmimage_image_settings_s::is_partition_table |
Define if the current "partition" is the partition table.
For partitions (CMD FD2000, FD4000), the partition table is handled as a directory. Thus, the directory processing functions must know if they handle the partition table (== this is set to 1) or not (== 0)
◆ maxsectors
| uint16_t cbmimage_image_settings_s::maxsectors |
maximum number of sectors (e.g. 21 if sectors go from 0 to 20). Note that the number of sectors in a specific track can be lower than this.
◆ subdir_data_offset
| size_t cbmimage_image_settings_s::subdir_data_offset |
data offset for subdir
For subdirs/partitions that are handled as part of an absolute section on the image (e.g., FD2000/FD4000 D64, D71 or D81 partitions), this offset is added in order to get the address of a block in the partition.
If there is no subdir or no subdir is active, this must be 0.
◆ subdir_global_addressing
| unsigned int cbmimage_image_settings_s::subdir_global_addressing |
flag if there is an active subdir with absolute addresses
If this is 1, then subdirs/partitions are processed with absolute addresses (1581 style). That is: If the subdir starts at 3/0, then in the subdir, this block is named 3/0 and the link to the next block is 3/1.
If no subdir/partition is active, then this must be 0.
◆ subdir_relative_addressing
| unsigned int cbmimage_image_settings_s::subdir_relative_addressing |
flag if there is an active subdir with relative addresses
If this is != 0, there is an active subdir/partition that is processed with relative addresses (CMD Fdx000 style). That is: If the subdir starts at 3/0, then in the subdir, this block is named 1/0 and the link to the next block is 1/1.
If no subdir/partition is active, this must be 0.
