load_wav_pf(3alleg4)

💖 load_wav_pf — the packfile glow-up of load_wav 💖

okay so bestie, you're in the Allegro manual, section 3alleg4, and today's main character is load_wav_pf — the packfile version of load_wav, from the Allegro game programming library. yes she's a function. yes she eats .wav files straight out of a packfile. iconic behavior honestly.

✨ SYNOPSIS ✨

#include <allegro.h>

SAMPLE *load_wav_pf(PACKFILE *f);

like, that's the whole vibe. one packfile in, one SAMPLE out. no cap.

🌸 DESCRIPTION 🌸

so load_wav_pf() is literally just load_wav() but it reads from a packfile instead of a regular file. same energy, different door. if you've already got a PACKFILE * open and you want a sound out of it, this is your girl. 🎀

here's how it looks in the wild:

PACKFILE *packfile;
SAMPLE *sample;

packfile = pack_fopen("sound.wav", F_READ);
if (!packfile)
   abort_on_error("Couldn't open sound.wav");

sample = load_wav_pf(packfile);
if (!sample)
   abort_on_error("Error loading sound.wav");

see how we open with pack_fopen and F_READ first, then hand the packfile over? yeah. that's the whole flow. and yes, the error checks are there for a reason — abort_on_error is your bestie when things go sideways. 😭

🫶 RETURN VALUE 🫶

she returns a pointer to the SAMPLE, or NULL if something went wrong. periodt.

⚠️ okay this part is IMPORTANT, don't scroll past it: remember to free this sample later or you will have a memory leak. and memory leaks are not cute. they are the opposite of cute. free your sample, bestie. 💅
