uszprintf3alleg4

Usage

Overview

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.
