open_write(3)

💖 open_write(3) 💖

okay so bestie, we're in the Library Functions Manual today and this page is called open_write — it's giving "tiny function, huge main character energy" and honestly? it ate. ✨

---

🌸 NAME 🌸

open_write — open a file for writing 🖊️✨

---

🎀 SYNTAX 🎀

bestie the setup is literally this:

#include <libowfat/open.h>

int open_write(const char *filename);

that's it. that's the whole vibe. 🦋

---

💅 DESCRIPTION 💅

so open_write opens the file filename for write-only use and hands you back the file handle. that's the whole job, and it does it flawlessly, no notes. 👑

if the file does not exist? not a problem, it will be created, with mode 0644. iconic behaviour. 🌈

and if something goes wrong while opening or creating the file — like, the vibe check failed — open_write returns -1 and sets errno accordingly. so always check your return value, bestie, don't just assume it worked. 😭💀
