<p class="level0">This function receives raw data from the established connection. You may use it together with <a Class="emphasis" href="./curl_easy_send.html">curl_easy_send</a> to implement custom protocols using libcurl. This functionality can be particularly useful if you use proxies and/or SSL encryption: libcurl will take care of proxy negotiation and connection set-up.
