This tells the user about its capabilities and can be used to determine strategies. </p> <h3>Usage</h3> <pre> curlVersion(id = 0) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>id</code></td> <td> <p>an integer value between 0 and 3 inclusive. The idea is that one specifies the identifier for the version of interest.
