CURLOPT_TIMECONDITION(3)   curl_easy_setopt options   CURLOPT_TIMECONDITION(3)

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 _TIMEVALUE&section=3">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. _easy_getinfo&section=3">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
