NAME
CURLOPT_CONNECTTIMEOUT_MS - timeout for the connect phase
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECTTIMEOUT_MS, long timeout);
DESCRIPTION
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.
DEFAULT
300000
PROTOCOLS
All
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* complete connection within 10000 milliseconds */
curl_easy_setopt(curl, CURLOPT_CONNECTTIMEOUT, 10000L);
curl_easy_perform(curl);
}
