# Varargs (`...args`)

Silk supports “varargs” parameters to accept a variable number of trailing
arguments, used by [`std::io::print`](/silk/docs/std/io/) / [`std::io::println`](/silk/docs/std/io/).

Full reference: [varargs](/silk/wiki/language/varargs/).

## Syntax

fn log (fmt: string, ...args: std::fmt::Arg) -> void {
  std::io::println(fmt, args);
}
```

import std::io;

fn main () -> int {
  std::io::println("hello {s} answer={d}", "world", 42);
