uszprintf(3)

✨ uszprintf(3) ✨

okay so bestie, welcome to the Allegro manual 💖 this one's called uszprintf, and it lives in the Allegro game programming library 🎮✨ it's giving "format a string but, like, safely, with a size limit" and honestly? iconic. periodt.

---

🌸 NAME 🌸

uszprintf — writes formatted data into a buffer, specifying size. Allegro game programming library. no cap. 🫶

---

🎀 SYNOPSIS 🎀

#include <allegro.h>

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

---

💅 DESCRIPTION 💅

so 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 slay part: the buffer is guaranteed to be NULL terminated. literally guaranteed. she would never leave you hanging like that 💖

example time, because we love a demo:

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

see how she passes sizeof(buffer)? that's the vibe check 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 like, if your buffer was too smol and things got chopped, the return value still tells you the full length that would have existed. main character energy: she reports the whole truth even when the buffer can't hold it 😭👑

ngl bestie, if you're formatting into a fixed-size buffer and you don't wanna think about null termination ever again, this is your girl 💜
