|
|
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_TIMECONDITION \- select condition for a time request
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMECONDITION, long cond);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a long as parameter. This defines how the \fICURLOPT_TIMEVALUE(3)\fP time
|
||
|
|
value is treated. You can set this parameter to \fICURL_TIMECOND_IFMODSINCE\fP
|
||
|
|
or \fICURL_TIMECOND_IFUNMODSINCE\fP.
|
||
|
|
|
||
|
|
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 condition would not
|
||
|
|
have been met. \fIcurl_easy_getinfo(3)\fP with the
|
||
|
|
\fICURLINFO_CONDITION_UNMET\fP option can be used after a transfer to learn if
|
||
|
|
a zero-byte successful "transfer" was due to this condition not matching.
|
||
|
|
.SH DEFAULT
|
||
|
|
