# NAME
CURLOPT_FILETIME - get the modification time of the remote resource
# SYNOPSIS
~~~c
#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%
# EXAMPLE
~~~c
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);
}
}
~~~
# %AVAILABILITY%
# RETURN VALUE
curl_easy_setopt(3) returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
libcurl-errors(3).
