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)
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);
}
