<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.
<p class="level0"><span Class="bold">buffer</span> is a pointer to your buffer that will get the received data. <span Class="bold">buflen</span> is the maximum amount of data you can get in that buffer. The variable <span Class="bold">n</span> points to will receive the number of received bytes.
-<p class="level0">To establish the connection, set <span Class="
bold">CURLOPT_CONNECT_ONLY(3)</span> option before calling <a Class="emphasis" href="./curl_easy_perform.html">curl_easy_perform</a> or <a Class="emphasis" href="./curl_multi_perform.html">curl_multi_perform</a>. Note that <a Class="emphasis" href="./curl_easy_recv.html">curl_easy_recv</a> does not work on connections that were created without this option.
-<p class="level0">You must ensure that the socket has data to read before calling <a Class="emphasis" href="./curl_easy_recv.html">curl_easy_recv</a>, otherwise the call will return <span Class="bold">CURLE_AGAIN</span> - the socket is used in non-blocking mode internally. Use <a Class="emphasis" href="./curl_easy_getinfo.html">curl_easy_getinfo</a> with <span Class="
bold">CURLINFO_ACTIVESOCKET(3)</span> to obtain the socket; use your operating system facilities like <span Class="emphasis">select(2)</span> to check if it has any data you can read. <a name="AVAILABILITY"></a><h2 class="nroffsh">AVAILABILITY</h2>

<p class="level0">On success, returns <span Class="bold">CURLE_OK</span>, stores the received data into <span Class="bold">buffer</span>, and the number of bytes it actually read into <span Class="bold">*n</span>.
<p class="level0">On failure, returns the appropriate error code.
