+readdirex({directory} [, {expr} [, {dict}]]) *readdirex()*
+ Extended version of |readdir()|.
+ Return a list of Dictionaries with file and directory
+ information in {directory}.
+ This is useful if you want to get the attributes of file and
+ directory at the same time as getting a list of a directory.
+ This is much faster than calling |readdir()| then calling
+ |getfperm()|, |getfsize()|, |getftime()| and |getftype()| for
+ each file and directory especially on MS-Windows.
+ The list will by default be sorted by name (case sensitive),
+ the sorting can be changed by using the optional {dict}
+ argument, see |readdir()|.
+
+ The Dictionary for file and directory information has the
+ following items:
+ group Group name of the entry. (Only on Unix)
+ name Name of the entry.
+ perm Permissions of the entry. See |getfperm()|.
+ size Size of the entry. See |getfsize()|.
+ time Timestamp of the entry. See |getftime()|.
+ type Type of the entry.
+ On Unix, almost same as |getftype()| except:
+ Symlink to a dir "linkd"
+ Other symlink "link"
+ On MS-Windows:
+ Normal file "file"
+ Directory "dir"
+ Junction "junction"
+ Symlink to a dir "linkd"
+ Other symlink "link"
+ Other reparse point "reparse"
+ user User name of the entry's owner. (Only on Unix)
+ On Unix, if the entry is a symlink, the Dictionary includes
+ the information of the target (except the "type" item).
+ On MS-Windows, it includes the information of the symlink
+ itself because of performance reasons.
