|
|
- SplitparT which represents byte intervals of data files.
|
||
|
|
|
||
|
|
- DirseQ which crawls along a directory's content list.
|
||
|
|
|
||
|
|
- ExclusionS which manages the list of excluded file paths and
|
||
|
|
leaf patterns.
|
||
|
|
|
||
|
|
- Xorriso_lsT which provides a generic double-linked list.
|
||
|
|
|
||
|
|
- LinkiteM, PermiteM which temporarily record relations and states.
