uvsprintf(3alleg4)

💖 uvsprintf 💖

okay so bestie, welcome to uvsprintf — she lives in the Allegro manual and she's part of the Allegro game programming library. 🎀

She writes formatted data into a buffer, using variable arguments. Yes, that's the whole vibe. ✨

✨ NAME ✨

uvsprintf — writes formatted data into a buffer, using variable arguments, brought to you by the Allegro game programming library. 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

int uvsprintf(char *buf, const char *format, va_list args);

🦋 DESCRIPTION 🦋

so this one is literally like usprintf(), except — and this is the whole plot twist — you pass the variable argument list directly, instead of the arguments themselves. 😭

the way that this is useful?? you can use this function to implement printf-like functions, which are also called variadic functions. iykyk. 👑

but ngl bestie, you should try to avoid this function, because it is very easy to overflow the destination buffer. like, it's giving danger. 💀 instead, use uvszprintf. she's the safe one. 🫶

ok real talk, the buffer overflow thing is not a drill. no cap. protect your memory, protect your peace. 🌈

⭐ RETURN VALUE ⭐

she returns the number of characters written, not including the terminating null character. periodt. ✨
