NAME
       Archive::Zip::MemberRead - A wrapper that lets you read Zip archive
       members as if they were files.

SYNOPSIS
         use Archive::Zip;
         use Archive::Zip::MemberRead;
         $zip = Archive::Zip->new("file.zip");
         $fh  = Archive::Zip::MemberRead->new($zip, "subdir/abc.txt");
         while (defined($line = $fh->getline()))
         {
             print $fh->input_line_number . "#: $line\n";
         }

         $read = $fh->read($buffer, 32*1024);
         print "Read $read bytes as :$buffer:\n";

DESCRIPTION
       The Archive::Zip::MemberRead module lets you read Zip archive member
       data just like you read data from files.

METHODS
       Archive::Zip::Member::readFileHandle()
           You  can get a "Archive::Zip::MemberRead" from an archive member by
           calling "readFileHandle()":

             my $member = $zip->memberNamed('abc/def.c');
             my $fh = $member->readFileHandle();
             while (defined($line = $fh->getline()))
             {
                 # ...
             }
             $fh->close();

       Archive::Zip::MemberRead->new($zip, $fileName)
       Archive::Zip::MemberRead->new($zip, $member)
       Archive::Zip::MemberRead->new($member)
           Construct a new Archive::Zip::MemberRead on the specified member.

             my $fh = Archive::Zip::MemberRead->new($zip, 'fred.c')

       setLineEnd(expr)
           Set the line end character to use. This is set  to  \n  by  default
           except  on  Windows  systems where it is set to \r\n. You will only
           need to set this on systems which are not Windows or Unix based and
           require a line end different from \n.  This is a  class  method  so
           call as "Archive::Zip::MemberRead"->"setLineEnd($nl)"

       rewind()
           Rewinds  an "Archive::Zip::MemberRead" so that you can read from it
           again starting at the beginning.

       input_record_separator(expr)
           If the argument is given, input_record_separator for this  instance
           is  set  to it. The current setting (which may be the global $/) is
           always returned.

       input_line_number()
           Returns  the  current  line  number,  but  only  if  you're   using
           "getline()".  Using "read()" will not update the line number.

       close()
           Closes the given file handle.

       buffer_size([ $size ])
           Gets  or sets the buffer size used for reads.  Default is the chunk
           size used by Archive::Zip.

       getline()
           Returns the next line from the currently open member.  Makes  sense
           only  for  text  files.  A read error is considered fatal enough to
           die.  Returns undef on  eof.  All  subsequent  calls  would  return
           undef,  unless  a  rewind() is called.  Note: The line returned has
           the input_record_separator (default: newline) removed.

       getline( { preserve_line_ending => 1 } )
           Returns the next line including the line ending.

       read($buffer, $num_bytes_to_read)
           Simulates a normal "read()" system call.  Returns the no. of  bytes
           read. "undef" on error, 0 on eof, e.g.:

             $fh = Archive::Zip::MemberRead->new($zip, "sreeji/secrets.bin");
             while (1)
             {
               $read = $fh->read($buffer, 1024);
               die "FATAL ERROR reading my secrets !\n" if (!defined($read));
               last if (!$read);
               # Do processing.
               ....
              }
