`flags`::
- A bit-field of options:
+ A bit-field of options (the `*IGNORED*` flags are mutually exclusive):
`DIR_SHOW_IGNORED`:::
- The traversal is for finding just ignored files, not unignored
- files.
+ Return just ignored files in `entries[]`, not untracked files.
+
+`DIR_SHOW_IGNORED_TOO`:::
+
+ Similar to `DIR_SHOW_IGNORED`, but return ignored files in `ignored[]`
+ in addition to untracked files in `entries[]`.
+
+`DIR_COLLECT_IGNORED`:::
+
+ Special mode for git-add. Return ignored files in `ignored[]` and
+ untracked files in `entries[]`. Only returns ignored files that match
+ pathspec exactly (no wildcards). Does not recurse into ignored
+ directories.
`DIR_SHOW_OTHER_DIRECTORIES`:::
Internal use; keeps track of allocation of `entries[]` array.
+`ignored[]`::
+
+ An array of `struct dir_entry`, used for ignored paths with the
+ `DIR_SHOW_IGNORED_TOO` and `DIR_COLLECT_IGNORED` flags.
+
+`ignored_nr`::
+
+ The number of members in `ignored[]` array.
Calling sequence
----------------
* Prepare `struct dir_struct dir` and clear it with `memset(&dir, 0,
sizeof(dir))`.
-* Call `add_exclude()` to add single exclude pattern,
- `add_excludes_from_file()` to add patterns from a file
- (e.g. `.git/info/exclude`), and/or set `dir.exclude_per_dir`. A
- short-hand function `setup_standard_excludes()` can be used to set up
- the standard set of exclude settings.
+* To add single exclude pattern, call `add_exclude_list()` and then
+ `add_exclude()`.
+
+* To add patterns from a file (e.g. `.git/info/exclude`), call
+ `add_excludes_from_file()` , and/or set `dir.exclude_per_dir`. A
+ short-hand function `setup_standard_excludes()` can be used to set
+ up the standard set of exclude settings.
* Set options described in the Data Structure section above.
* Use `dir.entries[]`.
+* Call `clear_directory()` when none of the contained elements are no longer in use.
