<p class="level0"><a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">curl_formfree() is used to clean up data previously built/appended with <a class="emphasis" href="./curl_formadd.html">curl_formadd(3)</a>. This must be called when the data has been used, which typically means after <a class="emphasis" href="./curl_easy_perform.html">curl_easy_perform(3)</a> has been called. 
<p class="level0">The pointer to free is the same pointer you passed to the <span Class="bold">CURLOPT_HTTPPOST</span> option, which is the <span Class="emphasis">firstitem</span> pointer from the <a class="emphasis" href="./curl_formadd.html">curl_formadd(3)</a> invoke(s). 
<p class="level0"><span Class="bold">form</span> is the pointer as returned from a previous call to <a class="emphasis" href="./curl_formadd.html">curl_formadd(3)</a> and may be NULL. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
