<p class="level0">Pass a long as parameter containing <span Class="emphasis">timeout</span> - the maximum time in milliseconds that you allow the libcurl transfer operation to take. Normally, name lookups can take a considerable time and limiting operations to less than a few minutes risk aborting perfectly normal operations. This option may cause libcurl to use the SIGALRM signal to timeout system calls.
<p class="level0">If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second.
<p class="level0">In unix-like systems, this might cause signals to be used unless <a Class="emphasis" href="./CURLOPT_NOSIGNAL.html">CURLOPT_NOSIGNAL</a> is set.
<p class="level0">If both <a Class="emphasis" href="./CURLOPT_TIMEOUT.html">CURLOPT_TIMEOUT</a> and <a Class="emphasis" href="./CURLOPT_TIMEOUT_MS.html">CURLOPT_TIMEOUT_MS</a> are set, the value set last will be used.
<p class="level0">Since this puts a hard limit for how long time a request is allowed to take, it has limited use in dynamic use cases with varying transfer times. You are then advised to explore <a Class="emphasis" href="./CURLOPT_LOW_SPEED_LIMIT.html">CURLOPT_LOW_SPEED_LIMIT</a>, <a Class="emphasis" href="./CURLOPT_LOW_SPEED_TIME.html">CURLOPT_LOW_SPEED_TIME</a> or using <a Class="emphasis" href="./CURLOPT_PROGRESSFUNCTION.html">CURLOPT_PROGRESSFUNCTION</a> to implement your own timeout logic. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
<p class="level0">Default timeout is 0 (zero) which means it never times out during transfer. <a name="PROTOCOLS"></a><h2 class="nroffsh">PROTOCOLS</h2>
