2023-04-29Move type based filtering to libutil dir_tree_iterator_tDavid Oberhollenzer
Limited unit testing for the flags is added, particularly the abillity to recurse into sub-directories, but not report the parents as individual entries. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-29libutil: Add a stacked, recursive directory tree iteratorDavid Oberhollenzer
The concept is simple: Use the existing, platform dependent iterator to walk a directory. If a directory entry is encountered, recurse into it using the open_subdir handler, reconstruct the full path for any entries discovered using the directory stack. An additional function is added to skip a sub-hierarchy. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
