Subject: Feature: Add list support for directory recurse processing.
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=8e7b1035cd0b87b79df4afc32e9e0ab006ebd776;p=fll

Feature: Add list support for directory recurse processing.

The fl_directory_do() now provides support for the callback to handle the directory list process.
