If it is 1, libcurl will attempt to get the modification time of the remote document in this operation. This requires that the remote server sends the time or replies to a time querying command. The \fIcurl_easy_getinfo(3)\fP function with the \fICURLINFO_FILETIME(3)\fP argument can be used after a transfer to extract the received time (if any). .SH DEFAULT 0 .SH PROTOCOLS HTTP, FTP, SFTP, FILE .SH EXAMPLE .nf curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, url); /* Ask for filetime */ curl_easy_setopt(curl, CURLOPT_FILETIME, 1L); res = curl_easy_perform(curl); if(CURLE_OK == res) { res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime); if((CURLE_OK == res) && (filetime >= 0)) { time_t file_time = (time_t)filetime; printf("filetime %s: %s", filename, ctime(&file_time)); } } /* always cleanup */ curl_easy_cleanup(curl); } .fi .SH AVAILABILITY Always, for SFTP since 7.49.0 .SH RETURN VALUE Returns CURLE_OK .SH "SEE ALSO" .BR curl_easy_getinfo "(3), "
