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.
