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. 53<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. 54<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. 55<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. 56<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.
