- Returns a string which interpreting the extended attribute xa_attr.
- For example:
- \verbatim
- d---1xrxrxr
- ---2--r-r-r
- -a--1xrxrxr
- \endverbatim
-
- A description of the characters in the string follows
- The 1st character is either "d" if the entry is a directory, or "-" if not.
- The 2nd character is either "a" if the entry is CDDA (audio), or "-" if not.
- The 3rd character is either "i" if the entry is interleaved, or "-" if not.
- The 4th character is either "2" if the entry is mode2 form2 or "-" if not.
- The 5th character is either "1" if the entry is mode2 form1 or "-" if not.
- Note that an entry will either be in mode2 form1 or mode form2. That
- is you will either see "2-" or "-1" in the 4th & 5th positions.
-
- The 6th and 7th characters refer to permissions for a user while the
- the 8th and 9th characters refer to permissions for a group while, and
- the 10th and 11th characters refer to permissions for a others.
-
- In each of these pairs the first character (6, 8, 10) is "x" if the
- entry is executable. For a directory this means the directory is
- allowed to be listed or "searched".
- The second character of a pair (7, 9, 11) is "r" if the entry is allowed
- to be read.
