CURLOPT_SERVER_RESPONSE_TIMEOUT_MS - Man Page

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVER_RESPONSE_TIMEOUT_MS,
                          long timeout);

Pass a long. Causes libcurl to set a timeout period (in milliseconds) 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_SERVER_RESPONSE_TIMEOUT_MS(3) to a value smaller than CURLOPT_TIMEOUT(3).

The maximum accepted value is 2147483648.

This is the millisecond version of CURLOPT_SERVER_RESPONSE_TIMEOUT(3).

None

This functionality affects ftp, imap, pop3, scp, sftp and smtp

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/slow.txt");
    /* wait no more than 237 milliseconds */
    curl_easy_setopt(curl, CURLOPT_SERVER_RESPONSE_TIMEOUT_MS, 237L);
    res = curl_easy_perform(curl);

    curl_easy_cleanup(curl);
  }
}

Added in curl 8.6.0

Returns CURLE_OK if 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.
