uvszprintf - Writes formatted data into a buffer, using size and variable arguments. Allegro game

       This is like uszprintf(), but you pass the variable argument list  directly,  instead  of  the  arguments
       themselves. Example:

          #include <stdarg.h>

          void log_message(const char *format, ...)
          {
             char buffer[100];
             va_list parameters;

             va_start(parameters, format);
             uvszprintf(buffer, sizeof(buffer), format, parameters);
             va_end(parameters);

             append_buffer_to_logfile(log_name, buffer);
             send_buffer_to_other_networked_players(multicast_ip, buffer);
             and_also_print_it_on_the_screen(cool_font, buffer);
          }

          void some_other_function(void)
          {
             log_message("Hello %s, are you %d years old?\n", "Dave", 25);
          }

       uvszprintf  -  Writes  formatted  data  into  a  buffer,  using size and variable arguments. Allegro game
       programming library.

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