If it is 1, libcurl attempts to get the modification time of the 34remote document in this operation. This requires that the remote server sends 35the time or replies to a time querying command. The curl_easy_getinfo(3) 36function with the CURLINFO_FILETIME(3) argument can be used after a 37transfer to extract the received time (if any). 38 39# DEFAULT 40 410 42 43# %PROTOCOLS% 44 45# EXAMPLE 46 47~~~c 48int main(void) 49{ 50 CURL *curl = curl_easy_init(); 51 if(curl) { 52 CURLcode res; 53 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/path.html"); 54 /* Ask for filetime */ 55 curl_easy_setopt(curl, CURLOPT_FILETIME, 1L); 56 res = curl_easy_perform(curl); 57 if(CURLE_OK == res) { 58 long filetime; 59 res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime); 60 if((CURLE_OK == res) && (filetime >= 0)) { 61 time_t file_time = (time_t)filetime; 62 printf("filetime: %s", ctime(&file_time)); 63 } 64 } 65 /* always cleanup */ 66 curl_easy_cleanup(curl); 67 } 68} 69~~~ 70 71# %AVAILABILITY% 72 73# RETURN VALUE 74 75Returns CURLE_OK 76
