NAME¶
CURLOPT_FILETIME - get the modification time of the remote resource
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);
DESCRIPTION¶
Pass a long. 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 curl_easy_getinfo(3) function with the CURLINFO_FILETIME(3) argument can be used after a transfer to extract the received time (if any).
DEFAULT¶
0

EXAMPLE¶
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); }
AVAILABILITY¶
