pack_ferror(3alleg4)

✨ pack_ferror ✨

okay bestie, welcome to pack_ferror — a little function from the Allegro game programming library, manual section 3alleg4 💖. she's small, she's simple, and she's here to answer one very important question: did something go wrong on my stream?? 🫶

🌸 SYNOPSIS 🌸

#include <allegro.h>

int pack_ferror(PACKFILE *f);

🦋 DESCRIPTION 🦋

so here's the tea ☕: some functions out there report errors by just... returning EOF. which is lowkey a mess, because then you can't tell if you hit the actual end of the file or if something genuinely broke 😭.

that's why it's often better to split the vibe check into two:

• use pack_feof() to check explicitly for end of file 🎀
• use pack_ferror() to check for errors 💅

both of these functions peek at indicators that are part of the internal state of the stream, so they can correctly tell these different situations apart. no cap, that's the whole point — they actually know what's going on in there 👑

👑 RETURN VALUE 👑

returns nonzero if the error indicator for the stream is set — meaning an error has occurred during a previous operation on the stream 🔥. and if it returns zero? congrats bestie, no error indicator, you're good 🌈

ngl, this one's a boolean-flavored situation: nonzero = something went wrong at some point. keep that in mind, iykyk 💜

that's the whole page, bestie, we ate and left no crumbs 🍓🧚 — this was pack_ferror from Allegro, version 4.4.3, out here doing her little error-checking thing for the 3alleg4 manual. slay, periodt 💅✨
