ZIP_SOURCE_WRITE(3)

💖 zip_source_write(3) — bestie's guide to yeeting bytes into a zip source 💖

okay so this is zip_source_write(3), and it lives in libzip (-lzip) 🎀 it's giving "write data to zip source" energy and honestly? iconic.

---

✨ SYNOPSIS ✨

#include <zip.h>

zip_int64_t
zip_source_write(zip_source_t *source, const void *data,
    zip_uint64_t len);

---

🌸 DESCRIPTION 🌸

so like. zip_source_write() takes len bytes out of the buffer data and writes them into the zip source source, right at the current write offset. that's it. that's the whole vibe. 💅

⚠️ but bestie, LISTEN — your source has to be prepared for writing first. you have to call zip_source_begin_write(3) before you do literally anything else. no begin_write, no write. that's the rule. 🫶

---

🔥 RETURN VALUES 🔥

if everything slays: you get back the number of bytes written ✨

if it does NOT slay: you get -1 back, and the error info inside source gets set to tell you what went wrong 😭 (it's giving "read the error, bestie").
