Using pointer to channel : <p>Is it good practice to use pointer to channel? For example I read the data concurrently and pass those data <code>map[string]sting</code> using channel  and process this channel inside <code>getSameValues()</code>.</p>

<pre><code>func getSameValues(results *chan map[string]string) []string {
    var datas = make([]map[string]string, len(*results))
    i := 0
    for values := range *results {
        datas[i] = values
        i++
    }
}
</code></pre>

<p>The reason I do this is because the <code>chan map[string]string</code> there will be around millions of data inside the map and it will be more than one map. </p>

<p>So I think it would be a good approach if I can pass pointer to the function so that it will not copy the data to save some resource of memory.</p>

<p>I didn't find a good practice in <a href="https://golang.org/doc/effective_go.html#channels" rel="noreferrer">effective go</a>. So I'm kinda doubt about my approach here. </p>
