ZIP_SOURCE_SEEK_WRITE(3)

✨ ZIP_SOURCE_SEEK_WRITE(3) ✨

okay bestie, we're doing the zip_source_seek_write page from the library functions manual, and honestly? it's a little bop. it's in libzip, obvi, and it's the one that moves your write cursor around like it owns the place 💅

---

🎀 NAME 🎀

zip_source_seek_write — set write offset in zip source

like, it literally just repositions where the next write is gonna land. that's the whole job. main character behaviour fr.

---

🦋 LIBRARY 🦋

libzip (-lzip)

link against it, bestie, that's the vibe.

---

✨ SYNOPSIS ✨

#include <zip.h>

int
zip_source_seek_write(zip_source_t *source, zip_int64_t offset,
    int whence);

look at that signature. source, offset, whence. three little guys, one big destiny 🫶

---

💖 DESCRIPTION 💖

so the function zip_source_seek_write() sets the current write offset for source. that's it, that's the tea 🍓

and listen — it works just like fseek(3). so depending on what you pass as the whence argument, the offset gets counted relative from one of these iconic little spots:

• SEEK_SET — start of file 🏁
• SEEK_CUR — current write offset in file 📍
• SEEK_END — end of file 🔚

pick your anchor point, pick your distance, go. no cap.

---

💀 RETURN VALUES 💀

• upon successful completion, 0 is returned 🎉 slay.
• otherwise, -1 is returned and the error information in source is set to indicate the error 😭 so like, check your errors, babe, they're right there in source.

ngl, -1 is the "not me, not today" of return values. don't ignore it.
