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 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); } AVAILABILITY Always RETURN VALUE Returns CURLE_OK ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | web/curl | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO CURLOPT_TIMEVALUE(3), NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
