CURLOPT_SE...TIMEOUT_MS(3)  Library Functions Manual  CURLOPT_SE...TIMEOUT_MS(3)

NAME
     CURLOPT_SERVER_RESPONSE_TIMEOUT_MS	 -  time  allowed to wait for server re-
     sponse

SYNOPSIS
     #include <curl/curl.h>

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

DESCRIPTION
     Pass a long. It tells libcurl to wait no longer than  timeout  milliseconds
     for  responses on sent commands. If no response is received within this pe-
     riod, the connection is considered dead and the transfer fails.

     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 CUR-
     LOPT_TIMEOUT(3).

     The maximum accepted value is 2147483648.

     This is the millisecond version of CURLOPT_SERVER_RESPONSE_TIMEOUT(3).

DEFAULT
     60000 milliseconds

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

EXAMPLE
     int main(void)
     {
       CURL *curl = curl_easy_init();
       if(curl) {
	 CURLcode result;
	 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);
	 result = curl_easy_perform(curl);

	 curl_easy_cleanup(curl);
       }
     }

AVAILABILITY
     Added in curl 8.6.0

     curl_easy_setopt(3) returns a CURLcode indicating success or error.
