NAME
    IO::Dirent - Access to dirent structs returned by readdir

SYNOPSIS
      use IO::Dirent;

      opendir DIR, "/usr/local/foo";
      my @entries = readdirent(DIR);
      closedir DIR;

      print $entries[0]->{name}, "\n";
      print $entries[0]->{type}, "\n";
      print $entries[0]->{inode}, "\n";

DESCRIPTION
    IO::Dirent exports the following symbols by default:

        readdirent nextdirent

    readdirent returns a list of hashrefs. Each hashref contains the
    name of the directory entry, its inode for the filesystem it
    resides on and its type (if available). If the file type or inode
    are not available, it won't be there!

    nextdirent is an enumerator for a directory handle.

    The following tags may be exported to your namespace:

        ALL

    which includes readdirent and the following symbols:

        DT_UNKNOWN
        DT_FIFO
        DT_CHR
        DT_DIR
        DT_BLK
        DT_REG
        DT_LNK
        DT_SOCK
        DT_WHT

    These symbols can be used to test the file type returned by readdirent
    in the following manner:

        for my $entry ( readdirent(DIR) ) {
            next unless $entry->{'type'} == DT_LNK;

            print $entry->{'name'} . " is a symbolic link.\n";
        }

    Or by nextdirent in the same way:

        while( my $entry = nextdirent(DIR) ) {
            next unless $entry->{'type'} == DT_LNK;

            print $entry->{'name'} . " is a symbolic link.\n";
        }


    For platforms that do not implement file type in its dirent struct,
    readdirent will return a hashref with a single key/value of 'name' and
    the filename (effectively the same as readdir). This is subject to
    change, if I can implement some of the to do items below.

CAVEATS
    This was written on FreeBSD and OS X which implement a robust (but
    somewhat non-standard) dirent struct and which includes a file
    type entry. I have plans to make this module more portable and
    useful by doing a stat on each directory entry to find the file
    type and inode number when the dirent.h does not implement it
    otherwise.

    Improvements and additional ports are welcome.

BUILDING

    On OS X and recent Apple hardware, the undocumented ARCHFLAGS
    environment variable was valuable; without it, Perl would attempt
    to build i386 and ppc versions (which didn't work on my hardware):

        ARCHFLAGS="-arch x86_64" perl Makefile.PL

    I'd be happy to know if anyone knows of a way to detect this and
    set it during Makefile.PL.

TO DO
    *   For platforms that do not implement a dirent struct with file type,
        do a stat on the entry and populate the structure anyway.

    *   Do some memory profiling (I'm not sure if I have any leaks or not).
