uszprintf(3alleg4)

💖 uszprintf — the Allegro manual, but make it cute 💖

okay bestie, so this is uszprintf from the Allegro manual (that's section 3alleg4 of the man pages, iykyk) — and it's the Allegro game programming library's very own "write formatted stuff into a buffer, but like, tell it how big the buffer is" situation. she's giving safety girlie. she's giving I will not let you overflow. obsessed. 🎀

✨ NAME ✨

uszprintf — writes formatted data into a buffer, specifying size. part of the Allegro game programming library. 💅

🌸 SYNOPSIS 🌸

#include <allegro.h>

int uszprintf(char *buf, int size, const char *format, ...);

🦋 DESCRIPTION 🦋

so like. this function writes formatted data into the output buffer, and the length of that buffer in bytes is specified by size. and here's the iconic part: the result is guaranteed to be NULL terminated. no cap. periodt. 💖

example time, bestie:

char buffer[10];
int player_score;
...
uszprintf(buffer, sizeof(buffer), "Your score is: %d", player_score);

see how she passed sizeof(buffer)? that's the whole vibe. main character energy right there. 👑

🌈 RETURN VALUE 🌈

she returns the number of characters that would have been written without eventual truncation (like with usprintf), not including the terminating null character. so if your buffer was too small, she still tells you how much room you actually needed. so thoughtful. so generous. 🫶

mwah 💜 that's the whole page! this was Allegro, version 4.4.3, and the page itself is uszprintf(3alleg4) — so if you see that header/footer floating around, that's just her signature. slay, go format something safely. ✨🎀🦋
