uszprintf
Writes formatted data into a buffer, specifying size.
Description
int uszprintf(char *buf,
int size,
const char *format, ...
);
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);
Returns the number of characters that would have been written without
eventual truncation (like with usprintf), not including the terminating
null character.
