✨ NAME ✨

okay so bestie, welcome to io_appendfile(3) from the Library Functions Manual. The whole assignment? open a file for appending. That's it. That's the vibe. no cap. 💖

🦋 SYNTAX 🦋

#include <libowfat/io.h>

int io_appendfile(int64* d,const char* filename);

💅 DESCRIPTION 💅

vibe check: io_appendfile sets d to the number of a new descriptor that writes to the end of the disk file named filename, and returns 1. Iconic. Obsessed. ✨

And if that file does not exist? Not me being helpful — it will be created with mode 0600. 🎀

But if something goes wrong, bestie, it's giving error. 😭 io_appendfile sets errno to indicate the error, and returns 0. It does not create a new descriptor, and it does not touch d. d stays exactly where it was. periodt. 💅
