CURLOPT_CONNECTTIMEOUT_MS - timeout for the connect phase
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECTTIMEOUT_MS,
long timeout);
Pass a long. It should contain the maximum time in milliseconds that you allow
the connection phase to the server to take. This only limits the connection
phase, it has no impact once it has connected. Set to zero to switch to the
default built-in connection timeout - 300 seconds. See also the
CURLOPT_TIMEOUT_MS(3) option.
In unix-like systems, this might cause signals to be used unless
CURLOPT_NOSIGNAL(3) is set.
If both CURLOPT_CONNECTTIMEOUT(3) and
CURLOPT_CONNECTTIMEOUT_MS(3) are set, the value set last will be
used.
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* complete connection within 10000 milliseconds */
curl_easy_setopt(curl, CURLOPT_CONNECTTIMEOUT_MS, 10000L);
curl_easy_perform(curl);
