6  * @section c_dir_create Creating Directories
7  *
8  * To create a directory at a specific location, call @c le_dir_Make() passing in the path name of the
9  * directory to create. All directories in the path name except the last directory (the directory
10  * to be created) must exist prior to calling le_dir_Make().
11  *
12  * To create all directories in a specified path use @c le_dir_MakePath().
13  *
14  * With both le_dir_Make() and le_dir_MakePath() the calling process must have write and search
15  * permissions on all directories in the path.
16  *
17  * @section c_dir_delete Removing Directories
18  *
19  * To remove a directory and everything in the directory (including all files and sub-directories)
20  * use @c le_dir_RemoveRecursive().
21  *
22  * @section c_dir_read Reading Directories
23  *
24  * To read the contents of a directory use the POSIX function @c openDir().
