The package defines a new type

The new <a href="/pkg/os/#ReadDir"><code>ReadDir</code></a>
function and the new
<a href="/pkg/os/#File.ReadDir"><code>File.ReadDir</code></a>
method can be used to read the contents of a directory into a
slice of <a href="/pkg/os/#DirEntry"><code>DirEntry</code></a>.
The <a href="/pkg/os/#File.Readdir"><code>File.Readdir</code></a>
method (note the lower case <code>d</code> in <code>dir</code>)
still exists, returning a slice of
<a href="/pkg/os/#FileInfo"><code>FileInfo</code></a>, but for
most programs it will be more efficient to switch to
<a href="/pkg/os/#File.ReadDir"><code>File.ReadDir</code></a>.

The types <a href="/pkg/os/#FileInfo"><code>FileInfo</code></a>,
