pack_fwrite(3)

✨ pack_fwrite — the Allegro manual, bestie edition ✨

okay so real quick, this page lives in the Allegro manual, and today's main character is pack_fwrite(3). she writes bytes. she's simple. she's iconic. let's get into it 💅

🌸 NAME 🌸

pack_fwrite — writes n bytes to the stream. from the Allegro game programming library, obviously 🎀

🦋 SYNOPSIS 🦋

#include <allegro.h>

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

💖 DESCRIPTION 💖

so like, she takes n bytes from the memory location that p is pointing at, and she writes them straight into the stream f. that's it. that's the whole vibe. memory goes in, stream comes out, no cap 🌈

⭐ RETURN VALUE ⭐

she hands you back the number of bytes actually written, and if an error happens that number will be less than n — so watch for that, fr fr 😭

and the error codes? those get stored in errno. so if something's giving, check errno, she left the receipts there 💀

and that's the whole page bestie, go write some bytes 💖

okay so this was Allegro, version 4.4.3, and that footer is literally just the source and version, so there it is — mwah, bye 🫶✨
