uvszprintf

Writes formatted data into a buffer, using size and variable arguments.

Description

int uvszprintf(char *buf, int size, const char *format, va_list args);
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);
      }
Returns the number of characters that would have been written without eventual truncation (like with uvsprintf), not including the terminating null character.
