uvszprintf(3alleg4)						  Allegro manual					       uvszprintf(3alleg4)

NAME

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

SYNOPSIS

       #include <allegro.h>

       int uvszprintf(char *buf, int size, const char *format, va_list args);

DESCRIPTION

       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?
", "Dave", 25);
	  }

RETURN VALUE

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