CURLcode curl_easy_setopt(CURL *handle, CURLOPT_EXPECT_100_TIMEOUT_MS,

server response with the HTTP status 100 (Continue), 417 (Expectation
Failed) or similar after sending an HTTP request containing an
Expect: 100-continue header. If this times out before a response is
received, the request body is sent anyway.

curl_easy_setopt(curl, CURLOPT_EXPECT_100_TIMEOUT_MS, 3000L);

}
}
