<p> This function is the equivalent of a <code>readdir(2)</code> for a realdir
<br /> or a zipfile referenced by the ZZIP_DIR returned from <a href="#zzip_opendir"><code>zzip_opendir</code></a>.
<p>
The ZZIP_DIR handle (as returned by <a href="#zzip_opendir"><code>zzip_opendir)</code></a> contains a few more
<br /> entries than being copied into the ZZIP_DIRENT. The only valid fields in
<br /> a ZZIP_DIRENT are d_name (the file name), d_compr (compression), d_csize
<br /> (compressed size), st_size (uncompressed size).

<dd><p> (../zzip/dir.c)
<p> This function is the equivalent of <code>opendir(3)</code> for a realdir or zipfile.
<br /> <p>
This function has some magic - if the given argument-path
<br /> is a directory, it will wrap a real <code>opendir(3)</code> into the ZZIP_DIR
<br /> structure. Otherwise it will divert to <a href="#zzip_dir_open"><code>zzip_dir_open</code></a> which
<br /> can also attach a ".zip" extension if needed to find the archive.
<br /> <p>
the error-code is mapped to <code>errno(3)</code>.

<p> This function will <code>fopen(3)</code> a real/zipped file.
<p>
It has some magic functionality builtin - it will first try to open
<br /> the given <em>filename</em> as a normal file. If it does not
<br /> exist, the given path to the filename (if any) is split into
<br /> its directory-part and the file-part. A ".zip" extension is
<br /> then added to the directory-part to create the name of a
<br /> zip-archive. That zip-archive (if it exists) is being searched
<br /> for the file-part, and if found a zzip-handle is returned.
<p>
Note that if the file is found in the normal fs-directory the
<br /> returned structure is mostly empty and the <a href="#zzip_read"><code>zzip_read</code></a> call will
<br /> use the libc <code>read</code> to obtain data. Otherwise a <a href="#zzip_file_open"><code>zzip_file_open</code></a>
<br /> is performed and any error mapped to <code>errno(3)</code>.
<p>
unlike the posix-wrapper <a href="#zzip_open"><code>zzip_open</code></a> the mode-argument is
<br /> a string which allows for more freedom to support the extra
<br /> zzip modes called ZZIP_CASEINSENSITIVE and ZZIP_IGNOREPATH.
<br /> Currently, this <a href="#zzip_fopen"><code>zzip_fopen</code></a> call will convert the following
<br /> characters in the mode-string into their corrsponding mode-bits:
<br /> <ul><li><code> "r" : O_RDONLY : </code> read-only
<br /> </li><li><code> "b" : O_BINARY : </code> binary (win32 specific)
<br /> </li><li><code> "f" : O_NOCTTY : </code> no char device (unix)
<br /> </li><li><code> "i" : ZZIP_CASELESS : </code> inside zip file
<br /> </li><li><code> "*" : ZZIP_NOPATHS : </code> inside zip file only
<br /> </ul> all other modes will be ignored for zip-contained entries
<br /> but they are transferred for compatibility and portability,
<br /> including these extra sugar bits:
<br /> <ul><li><code> "x" : O_EXCL :</code> fail if file did exist
<br /> </li><li><code> "s" : O_SYNC :</code> synchronized access
<br /> </li><li><code> "n" : O_NONBLOCK :</code> nonblocking access
<br /> </li><li><code> "z#" : compression level :</code> for zlib
<br /> </li><li><code> "g#" : group access :</code> unix access bits
<br /> </li><li><code> "u#" : owner access :</code> unix access bits
<br /> </li><li><code> "o#" : world access :</code> unix access bits
<br /> </ul>... the access bits are in traditional unix bit format
<br /> with 7 = read/write/execute, 6 = read/write, 4 = read-only.
<p>
The default access mode is 0664, and the compression level
<br /> is ignored since the lib can not yet write zip files, otherwise
<br /> it would be the initialisation value for the zlib deflateInit
<br /> where 0 = no-compression, 1 = best-speed, 9 = best-compression.
