<p class="level0"><span Class="bold">CURL *curl_easy_init( );</span> <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">This function must be the first function to call, and it returns a CURL easy handle that you must use as input to other functions in the easy interface. This call <span Class="bold">MUST</span> have a corresponding call to <a Class="emphasis" href="./curl_easy_cleanup.html">curl_easy_cleanup</a> when the operation is complete.
<p class="level0">If you did not already call <a Class="emphasis" href="./curl_global_init.html">curl_global_init</a>, <a Class="emphasis" href="./curl_easy_init.html">curl_easy_init</a> does it automatically. This may be lethal in multi-threaded cases, since <a Class="emphasis" href="./curl_global_init.html">curl_global_init</a> is not thread-safe, and it may result in resource problems because there is no corresponding cleanup.
<p class="level0">You are strongly advised to not allow this automatic behaviour, by calling <a Class="emphasis" href="./curl_global_init.html">curl_global_init</a> yourself properly. See the description in <span Class="bold">libcurl</span>(3) of global environment requirements for details of how to use this function. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0">If this function returns NULL, something went wrong and you cannot use the other curl functions. <a name="EXAMPLE"></a><h2 class="nroffsh">EXAMPLE</h2>
