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 attempts 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

PROTOCOLS

This functionality affects file, ftp, http, sftp and smb

EXAMPLE

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/path.html");
/* Ask for filetime */
curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
res = curl_easy_perform(curl);
if(CURLE_OK == res) {
long filetime;
res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
if((CURLE_OK == res) && (filetime >= 0)) {
time_t file_time = (time_t)filetime;
printf("filetime: %s", ctime(&file_time));
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
}
