ZZIP_DIRHANDLE(3) zziplib Function List ZZIP_DIRHANDLE(3)NAME
zzip_dirhandle, zzip_dirfd - ...
SYNOPSIS
#include <zzip/lib.h>
ZZIP_DIR * zzip_dirhandle((ZZIP_FILE * fp));
int zzip_dirfd((ZZIP_DIR * dir));
DESCRIPTION
The zzip_dirhandle function will just return fp->dir
If a ZZIP_FILE is contained within a zip-file that one will be a valid pointer, otherwise a NULL is returned and the ZZIP_FILE wraps a real
file.
The zzip_dirfd function will just return dir->fd
If a ZZIP_DIR does point to a zipfile then the file-descriptor of that zipfile is returned, otherwise a NULL is returned and the ZZIP_DIR
wraps a real directory DIR (if you have dirent on your system).

ZZIP_OPEN(3) zziplib Function List ZZIP_OPEN(3)NAME
zzip_open, zzip_open_ext_io, zzip_open_shared_io - ...
SYNOPSIS
#include <zzip/lib.h>
ZZIP_FILE * zzip_open((zzip_char_t * filename, int o_flags));
ZZIP_FILE * zzip_open_ext_io((zzip_char_t * filename, int o_flags, int o_modes, zzip_strings_t * ext, zzip_plugin_io_t io));
ZZIP_FILE *
zzip_open_shared_io((ZZIP_FILE * stream, zzip_char_t * filename, int o_flags, int o_modes, zzip_strings_t * ext, zzip_plugin_io_t io));
DESCRIPTION
The zzip_open_ext_io function uses explicit ext and io instead of the internal defaults, setting them to zero is equivalent to zzip_open
note that the two flag types have been split into an o_flags (for fcntl-like openflags) and o_modes where the latter shall carry the
zzip_flags and possibly accessmodes for unix filesystems. Since this version of zziplib can not write zipfiles, it is not yet used for
anything else than zzip-specific modeflags.
The zzip_open_ext_io function returns a new zzip-handle (use zzip_close to return it). On error the zzip_open_ext_io function will return
null setting errno(3).
If any ext_io handlers were used then the referenced structure should be static as the allocated ZZIP_FILE does not copy them.
The zzip_open_shared_io function takes an extra stream argument - if a handle has been then ext/io can be left null and the new stream
handle will pick up the ext/io. This should be used only in specific environment however since zzip_file_real does not store any
ext-sequence.
The benefit for the zzip_open_shared_io function comes in when the old file handle was openened from a file within a zip archive. When the
new file is in the same zip archive then the internal zzip_dir structures will be shared. It is even quicker, as no check needs to be done
anymore trying to guess the zip archive place in the filesystem, here we just check whether the zip archive's filepath is a prefix part of
the filename to be opened.
Note that the zzip_open_shared_io function is also used by zzip_freopen that will unshare the old handle, thereby possibly closing the
handle.
The zzip_open_shared_io function returns a new zzip-handle (use zzip_close to return it). On error the zzip_open_shared_io function will
return null setting errno(3).
