NAME

6       uvszprintf  - Writes formatted data into a buffer, using size and vari‐
7       able arguments. Allegro game programming library.
8

SYNOPSIS

10       #include <allegro.h>
11
12
13       int uvszprintf(char *buf, int size, const char *format, va_list args);
14

DESCRIPTION

16       This is like uszprintf(), but  you  pass  the  variable  argument  list
17       directly, instead of the arguments themselves. Example:
18
19          #include <stdarg.h>
20
21          void log_message(const char *format, ...)
22          {
23             char buffer[100];
24             va_list parameters;
25
26             va_start(parameters, format);
27             uvszprintf(buffer, sizeof(buffer), format, parameters);
28             va_end(parameters);
29
30             append_buffer_to_logfile(log_name, buffer);
31             send_buffer_to_other_networked_players(multicast_ip, buffer);
32             and_also_print_it_on_the_screen(cool_font, buffer);
33          }
34
35          void some_other_function(void)
36          {
37             log_message("Hello %s, are you %d years old?\n", "Dave", 25);
38          }
39

RETURN VALUE

41       Returns  the  number of characters that would have been written without
42       eventual truncation (like with uvsprintf), not including the  terminat‐
43       ing null character.
