57 <p class="level0">Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask limits what protocols libcurl may use in the transfer. This allows you to have a libcurl built to support a wide range of protocols but still limit specific transfers to only be allowed to use a subset of them. By default libcurl will accept all protocols it supports (<span Class="emphasis">CURLPROTO_ALL</span>). See also <a Class="emphasis" href="./CURLOPT_REDIR_PROTOCOLS.html">CURLOPT_REDIR_PROTOCOLS</a>.
