get_extension(3alleg4)

✨ get_extension ✨

okay bestie, welcome to the get_extension page of the Allegro manual (yes that's the manual name, get_extension(3alleg4), we're in the Allegro game programming library era and it's giving retro royalty 👑).

NAME — get_extension — returns a pointer to the extension of a filename. Part of the Allegro game programming library, obviously 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

char *get_extension(const char *filename);

🎀 DESCRIPTION 🎀

So what it does is it sniffs out the extension of the filename you hand it — and it does NOT care whether you gave it path info or not, it handles both, no cap 🫶. Here's the example straight from the source:

get_executable_name(name, sizeof(name));
allegro_message("The binary has the extension `%s'\n",
                get_extension(name));

💖 RETURN VALUE 💖

It hands you back a pointer to the exact spot inside filename where the extension kicks in ✨.

BUT — and listen, this is the plot twist 😭 — if there's no filename at all, or the thing just doesn't have an extension, you get a pointer to the trailing null character instead. Like, an empty vibe. Nothing to see here. 🌈
