# uszprintf(3alleg4)

Writes formatted data into a buffer, specifying size. Allegro game programming library.

## NAME

uszprintf - Writes formatted data into a buffer, specifying size. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

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

## DESCRIPTION

This function writes formatted data into the output buffer, whose length in bytes is specified by \`size' and which is guaranteed to be NULL terminated. Example:

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

## RETURN VALUE

Returns the number of characters that would have been written without eventual truncation (like with usprintf), not including the terminating null character.
