# Ref::Util::XS(3pm)

XS implementation for Ref::Util

## NAME

Ref::Util::XS - XS implementation for Ref::Util

## VERSION

version 0.117

## SYNOPSIS

```
    use Ref::Util;
    # Don't use Ref::Util::XS directly!
    if (is_arrayref($something) {
        print for @$something;
    }
    elsif (is_hashref($something)) {
        print for sort values %$something;
    }
```

## DESCRIPTION

Ref::Util::XS is the XS implementation of Ref::Util, which provides several functions to help identify references in a more convenient way than the usual approach of examining the return value of `"ref"`.

You should use Ref::Util::XS by installing Ref::Util itself: if the system you install it on has a C compiler available, `"Ref::Util::XS"` will be installed and used automatically, providing a significant speed boost to everything that uses `"Ref::Util"`.

See Ref::Util for full documentation of the available functions.
