CURLOPT_FILETIME explained

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 function with the CURLINFO_FILETIME argument can be used after a transfer to extract the received time (if any).

Default

Protocols

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

Example

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

Availability

Added in curl 7.5

Return value

curl_easy_setopt returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors.
