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 \fICURLOPT_TIMEOUT(3)\fP option. In unix-like systems, this might cause signals to be used unless \fICURLOPT_NOSIGNAL(3)\fP is set. If both \fICURLOPT_CONNECTTIMEOUT(3)\fP and \fICURLOPT_CONNECTTIMEOUT_MS(3)\fP are set, the value set last will be used. The "connection phase" is considered complete when the requested TCP, TLS or QUIC handshakes are done. .SH DEFAULT 300 .SH PROTOCOLS All .SH EXAMPLE .nf 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); } .fi .SH AVAILABILITY Always .SH RETURN VALUE 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. .SH "SEE ALSO" .BR CURLOPT_CONNECTTIMEOUT_MS "(3), " .BR CURLOPT_TIMEOUT "(3), " CURLOPT_LOW_SPEED_LIMIT "(3), "
