usprintf(3)

okay so bestie, welcome to the Allegro manual 💖 this page is all about usprintf(3) and it's giving formatted-data-into-a-buffer energy, but also it comes with a big ol' warning, so stay with me fr fr.

✨ NAME ✨

usprintf — writes formatted data into a buffer. Part of the Allegro game programming library, bestie. 🎀

🌸 SYNOPSIS 🌸

#include <allegro.h>

int usprintf(char *buf, const char *format, ...);

like, you include <allegro.h> and then you call it with a buffer, a format string, and whatever extra args you need. simple, right? well… keep reading. 👀

💅 DESCRIPTION 💅

okay so this function literally writes formatted data into the output buffer. A NULL character is written to mark the end of the string — iconic for termination, but also lowkey a whole situation. 😭

You should try to avoid this function because it is very easy to overflow the destination buffer. like, no cap, it's giving security nightmare and your bestie is not about that life. 🚫

⚠️ fr fr warning: this is super easy to overflow. Use uszprintf instead, periodt. 💅

👑 RETURN VALUE 👑

It returns the number of characters written, not including the terminating NULL character. so like, the count is cute but it does not include the null terminator, iykyk. ✨
