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_TIME-
       COND_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 con-
       dition  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)
