CURLOPT_FILETIME(3) curl_easy_setopt options CURLOPT_FILETIME(3) 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 PROTOCOLS HTTP, FTP, SFTP, FILE 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 Always, for SFTP since 7.49.0 RETURN VALUE Returns CURLE_OK ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | web/curl | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO curl_easy_getinfo(3), NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
