zzip_dir_fdopen(3)

✨ zzip_dir_fdopen — the fd reopen situation 💅

okay bestie, so this is a page straight out of the zziplib Function List, and today's main characters are zzip_dir_fdopen and zzip_dir_fdopen_ext_io. they do the fd reopen thing. let's get into it 🫶

🌸 NAME 🌸

zzip_dir_fdopen, zzip_dir_fdopen_ext_io — fd reopen, no cap.

---

✨ SYNOPSIS ✨

#include <zzip/lib.h>

ZZIP_DIR*
zzip_dir_fdopen(int fd, zzip_error_t* errcode_p)

ZZIP_DIR*
zzip_dir_fdopen_ext_io(int fd, zzip_error_t* errcode_p, zzip_strings_t* ext,
                       const zzip_plugin_io_t io)

---

🦋 DESCRIPTION 🦋

so zzip_dir_fdopen is the function that zzip_dir_open and zzip_opendir(2) literally call. it opens the zip-archive as specified with the fd, and that fd points to a file that's already open, iykyk. then zzip_dir_fdopen goes and searches + parses the zip's central directory. iconic behavior honestly.

⚠️ NOTE: refcount is zero, so an _open/_close pair will also delete this _dirhandle. like, the close really said "and I took that personally" 😭 plan accordingly.

and the zzip_dir_fdopen_ext_io function? she uses explicit ext and io instead of the internal defaults. setting those to zero is equivalent to just calling zzip_dir_fdopen. so if you're feeling lazy, zero is your bestie. 💖
