CURLOPT_TIMEVALUE_LARGE(3) Library Functions Manual CURLOPT_TIMEVALUE_LARGE(3) NAME CURLOPT_TIMEVALUE_LARGE - time value for conditional SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE_LARGE, curl_off_t val); DESCRIPTION Pass a curl_off_t val as parameter. This should be the time counted as sec- onds since 1 Jan 1970, and the time is used in a condition as specified with CURLOPT_TIMECONDITION(3). The difference between this option and CURLOPT_TIMEVALUE(3) is the type of the argument. On systems where 'long' is only 32 bits wide, this option has to be used to set dates beyond the year 2038. DEFAULT 0 PROTOCOLS This functionality affects http only EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode result; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); /* January 1, 2020 is 1577833200 */ curl_easy_setopt(curl, CURLOPT_TIMEVALUE_LARGE, (curl_off_t)1577833200); /* If-Modified-Since the above time stamp */ curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE); /* Perform the request */ result = curl_easy_perform(curl); curl_easy_cleanup(curl); } } HISTORY CURL_TIMECOND_* enums became long types in 8.13.0, prior to this version a long cast was necessary when passed to curl_easy_setopt(3). AVAILABILITY Added in curl 7.59.0 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
