NAME

       CURLOPT_TIMECONDITION - select condition for a time request

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMECONDITION, long cond);

DESCRIPTION

       Pass a long as parameter. This defines how the CURLOPT_TIMEVALUE(3) time value is treated.
       You can set this parameter to CURL_TIMECOND_IFMODSINCE or CURL_TIMECOND_IFUNMODSINCE.

       The last modification time of a file is not  always  known  and  in  such  instances  this
       feature  will  have  no  effect  even if the given time condition would not have been met.
       curl_easy_getinfo(3) with the CURLINFO_CONDITION_UNMET option can be used after a transfer
       to learn if a zero-byte successful "transfer" was due to this condition not matching.

DEFAULT

       CURL_TIMECOND_NONE (0)

PROTOCOLS

       HTTP, FTP, RTSP, and FILE

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* January 1, 2020 is 1577833200 */
         curl_easy_setopt(curl, CURLOPT_TIMEVALUE, 1577833200L);

         /* If-Modified-Since the above time stamp */
         curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE);

         /* Perform the request */
         curl_easy_perform(curl);
