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.
