Alas, if this returns a 1 you know that the reason you didn't get data in return is because it didn't fulfill the condition. The long this argument points to will get a zero stored if the condition instead was met. .SH PROTOCOLS HTTP and some .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "http://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 */ res = curl_easy_perform(curl); if(!res) { /* check the time condition */ long unmet; res = curl_easy_getinfo(curl, CURLINFO_CONDITION_UNMET, &unmet); if(!res) { printf("The time condition was %sfulfilled\\n", unmet?"NOT":""); } } } .fi .SH AVAILABILITY Added in 7.19.4 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR curl_easy_getinfo "(3), " curl_easy_setopt "(3), "
