CURLOPT_FTP_RESPONSE_TIMEOUT - time allowed to wait for FTP response
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTP_RESPONSE_TIMEOUT,
long timeout);
Pass a long. Causes libcurl to set a timeout period (in seconds) on the
amount of time that the server is allowed to take in order to send a response
message for a command before the session is considered dead. While libcurl is
waiting for a response, this value overrides CURLOPT_TIMEOUT(3). It is
recommended that if used in conjunction with CURLOPT_TIMEOUT(3), you
set CURLOPT_FTP_RESPONSE_TIMEOUT(3) to a value smaller than
CURLOPT_TIMEOUT(3).
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/slow.txt");
/* wait no more than 23 seconds */
curl_easy_setopt(curl, CURLOPT_FTP_RESPONSE_TIMEOUT, 23L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
Returns CURLE_OK if FTP is supported, and CURLE_UNKNOWN_OPTION if not. Returns
CURLE_BAD_FUNCTION_ARGUMENT if set to a negative value or a value that when
converted to milliseconds is too large.
