+/* filemodestring - fill in string STR with an ls-style ASCII
+ representation of the st_mode field of file stats block STATP.
+ 12 characters are stored in STR.
+ The characters stored in STR are:
+
+ 0 File type, as in ftypelet above, except that other letters are used
+ for files whose type cannot be determined solely from st_mode:
+
+ 'F' semaphore
+ 'M' migrated file (Cray DMF)
+ 'Q' message queue
+ 'S' shared memory object
+ 'T' typed memory object
+
+ 1 'r' if the owner may read, '-' otherwise.
+
+ 2 'w' if the owner may write, '-' otherwise.
+
+ 3 'x' if the owner may execute, 's' if the file is
+ set-user-id, '-' otherwise.
+ 'S' if the file is set-user-id, but the execute
+ bit isn't set.
+
+ 4 'r' if group members may read, '-' otherwise.
+
+ 5 'w' if group members may write, '-' otherwise.
+
+ 6 'x' if group members may execute, 's' if the file is
+ set-group-id, '-' otherwise.
+ 'S' if it is set-group-id but not executable.
+
+ 7 'r' if any user may read, '-' otherwise.
+
+ 8 'w' if any user may write, '-' otherwise.
+
+ 9 'x' if any user may execute, 't' if the file is "sticky"
+ (will be retained in swap space after execution), '-'
+ otherwise.
+ 'T' if the file is sticky but not executable.
+
+ 10 ' ' for compatibility with 4.4BSD strmode,
+ since this interface does not support ACLs.
+
+ 11 '\0'. */
