Directory Tree Removal Library Module

The directory tree removal library module has the file name armtree.c. This module will remove an entire directory tree from a disk. Be very careful with this API. You can easily delete the entire contents of the disk by starting the deletion from the root of the drive.

This API uses the directory scanning API to navigate through the directory tree.

This API makes two passes through the directory tree. The first pass deletes all the files and stores all directory names in a link list (new entries are added to the top of the list [lifo]). The second pass goes through the link list from the top and deletes all the directories.

This API is mutli-platform and will compile in any environment that supports the POSIX 1003.1 directory system calls which are used by the directory scanning API.

This API has been built to use the logging manager if active.

Here is a list of functions in the directory tree removal library module:
