.SH NAME
uvszprintf \- Writes formatted data into a buffer, using size and variable arguments. Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B int uvszprintf(char *buf, int size, const char *format, va_list args);
.SH DESCRIPTION
This is like uszprintf(), but you pass the variable argument list
directly, instead of the arguments themselves. Example:

.nf
   #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);
   }
.fi
.SH "RETURN VALUE"
Returns the number of characters that would have been written without
eventual truncation (like with uvsprintf), not including the terminating
null character.
