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

MMEETTHHOODDSS
       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')

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

       inputlinenumber()
           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.

       buffersize([ $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 newline removed.

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

             $fh = new Archive::Zip::MemberRead($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.
               ....
              }
