ZIP_SOURCE_READ(3)

✨ zip_source_read(3) ✨

ok so bestie, welcome to the <pink>zip_source_read</pink> page — that's the manual page for <pink>zip_source_read</pink> from the <lavender>Library Functions Manual</lavender>, living in <mint>libzip</mint>. grab a snack, we're reading bytes 💅

---

🌸 NAME 🌸

zip_source_read — read data from a zip source 🦋

---

📚 LIBRARY 📚

libzip (-lzip) — link it and you're golden ✨

---

🎀 SYNOPSIS 🎀

#include <zip.h>

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

---

💖 DESCRIPTION 💖

ok so <pink>zip_source_read()</pink> is literally the "gimme the bytes" function. it reads up to len bytes of data from source, at the current read offset, straight into the buffer data. that's it, that's the whole vibe 🫶

⚠️ but listen — the zip source source has to be opened for reading first, by calling zip_source_open(3). no open, no read. periodt 💀

---

🌈 RETURN VALUES 🌈

• ✅ if it goes well, you get the number of bytes read back. slay.
• 🍓 if you call <pink>zip_source_read()</pink> after you've already hit the end of the file, you get 0. that's the "nothing left bestie" signal.
• 😭 otherwise you get -1, and the error information inside source gets set to tell you what went wrong. not the vibe, but at least it tells you.
