After this is fixed, the correct usage seems to be:

<?php
$zzip = zzip_opendir("foo.zip");

if($zzip)
{ 
  while ($zzip_entry = zzip_readdir($zzip))
  {
    echo "zzip_entry_name: " . zzip_entry_name($zzip_entry) . "\n";
    echo "zzip_entry_filesize: " . zzip_entry_filesize($zzip_entry) . "\n";

    if(zzip_open($zzip, $zzip_entry, "r"))
    {
      $buf = zzip_read($zzip_entry, zzip_entry_filesize($zzip_entry));
      zzip_close($zzip_entry);
      echo "read: " . strlen($buf) . " bytes\n";
    }
  }
  zzip_closedir($zzip);
}
?>

See patch at: http://pfft.net/robin/pub/zzip.patch

Then, correct use seems to be:
$zzip = zzip_opendir("foo.zip");
if($zzip)
{
  while ($zzip_entry = zzip_readdir($zzip))
  {
    echo "zzip_entry_name: " . zzip_entry_name($zzip_entry) . "n";
    echo "zzip_entry_filesize: " . zzip_entry_filesize($zzip_entry) . "n";

    if(zzip_open($zzip, $zzip_entry, "r"))
    {
      $buf = zzip_read($zzip_entry, zzip_entry_filesize($zzip_entry));
      zzip_close($zzip_entry);
      echo "read: " . strlen($buf) . " bytesn";
    }
  }
  zzip_closedir($zzip);
}
