zzip_tell(3)

💖 zzip_tell(3) — bestie edition 💖

okay so this is a page from the zziplib Function List manual, and today we're talking about the tell girlies: zzip_tell and zzip_tell32. no cap, they're literally just here to tell you where you are. 🎀

---

✨ NAME ✨

zzip_tell, zzip_tell32 — tell. that's it. that's the vibe. 💅

---

✨ SYNOPSIS ✨

#include <zzip/lib.h>

zzip_off_t
zzip_tell(ZZIP_FILE* fp)

long
zzip_tell32(ZZIP_FILE* fp)

ok so you pull in the header, then you've got two lil functions to choose from — the big one and the small one. slay. 🦋

---

✨ DESCRIPTION ✨

so zzip_tell is the moment where it goes tell(2) and reports the current position inside a real/zipped file. main character behaviour honestly.

it hands back the current offset within that real/zipped file, and if we're in the zipped-file situation, that offset is measured in uncompressed bytes. yes bestie, uncompressed — we're counting the vibes after decompression, not the squished bytes on disk. 💖

now here's the tea 🍓: if the file-handle is wrapping a file that's stat-able, it will lowkey just do a normal tell(2)-call like nothing happened. but if it's not stat-able, then the offset gets calculated from the amount of data left plus the total uncompressed size. either way you get your number, the path there just depends. ✨

and zzip_tell32? she's provided for the users who can't use any largefile-mode. a whole function just for y'all. iconic, honestly. 👑

ngl if you're on a largefile setup, zzip_tell is your girl. if you're not, zzip_tell32 has you. pick your fighter. 🫶
