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?\n", "Dave", 25);
          }

RETURN VALUE

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