CURLOPT_CONNECTTIMEOUT - timeout for the connect phase
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECTTIMEOUT, long timeout);
Pass a long. It should contain the maximum time in seconds 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(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 10 seconds */
curl_easy_setopt(curl, CURLOPT_CONNECTTIMEOUT, 10L);
curl_easy_perform(curl);
}
Returns CURLE_OK. Returns CURLE_BAD_FUNCTION_ARGUMENT if set to a negative value
or a value that when converted to milliseconds is too large.
