Stopping a hanging call?

<p>Hello. Is there a way to have some call that hangs the system(like reading from a channel) stop if data hasn&#39;t been received in some time? Thank you.</p> <hr/>**评论：**<br/><br/>bastiaanvv: <pre><p>A very simple example on how to do this: <a href="https://play.golang.org/p/f4-pq0OQWvj" rel="nofollow">https://play.golang.org/p/f4-pq0OQWvj</a></p> <p>This method basically waits for two channels at the same time. The timeout channel and the int channel. Each time the int channel receives a value a new timeout is started. This simple method should be fine to use as long as you don&#39;t plan on receiving thousands of values per second.</p></pre>HarwellDekatron: <pre><p>This is the right answer.</p></pre>hell_0n_wheel: <pre><p>Yes.</p></pre>Hc3ttp3302: <pre><p>How?</p></pre>lausan: <pre><p><a href="https://golang.org/ref/spec#Select_statements" rel="nofollow"><code>select</code></a> and <a href="https://golang.org/pkg/time/#After" rel="nofollow"><code>time.After</code></a> could do it</p></pre>hell_0n_wheel: <pre><p><a href="http://www.catb.org/esr/faqs/smart-questions.html" rel="nofollow">http://www.catb.org/esr/faqs/smart-questions.html</a></p></pre>
