Expand a little. - mention the type name of the return code - avoid stating which exact return codes that might be returned, as that varies over time, builds and conditions - avoid stating some always return OK - refer to the manpage documenting all the return codes Closes #15900

# NAME
|
|
|
|
CURLOPT_TIMEVALUE_LARGE - time value for conditional
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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
|
|
seconds 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.

|

/* January 1, 2020 is 1577833200 */
|
|
curl_easy_setopt(curl, CURLOPT_TIMEVALUE_LARGE, (curl_off_t)1577833200);

curl_easy_perform(curl);
