Timeout for expect: 100-continue response
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_EXPECT_100_TIMEOUT_MS, long milliseconds);
Pass a long to tell libcurl the number of milliseconds to wait for a server response with the HTTP status 100 (Continue), 417 (Expectation Failed) or similar after sending a HTTP request containing an Expect: 100-continue header. If this times out before a response is received, the request body is sent anyway.
Added in 7.36.0
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
