pack_fwrite(3alleg4)

✨ pack_fwrite — the Allegro manual's lil' byte-writer ✨

okay bestie, pull up a chair because this is a 3alleg4 situation and it's genuinely so simple you're gonna be obsessed 💖 this one lives in the Allegro manual, and it's basically the "just write the bytes, girl" function.

🎀 NAME 🎀

pack_fwrite — writes n bytes to the stream. Allegro game programming library. that's it, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

long pack_fwrite(const void *p, long n, PACKFILE *f);

like, look at her. three args, one return, zero drama ✨

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🫖 — pack_fwrite writes n bytes to the stream f, and it takes them straight from the memory location that p is pointing at. that's it!! that's the function!! she's a simple girl with a simple job and she does it flawlessly 💖

like. p says "here's where the bytes are at", n says "how many we talking", f says "yeah drop 'em in me", and the bytes are just... written. slay 👑

👑 RETURN VALUE 👑

she hands you back the number of bytes she actually wrote 🎀 and here's the important part, so listen up: that number will be less than n if an error happens. so if you asked for n bytes and got back fewer?? that's your red flag 🚩🚩

💀 the error codes get stashed in errno, so go check there. errno is literally giving main character energy in this situation — it's the one who knows what went wrong.
