uvszprintf man page

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


#include <allegro.h>

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);
   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.
