# SYNOPSIS
|
|
|
|
~~~c
|

|
~~~

# DESCRIPTION
|
|
|
|
Pass a pointer to a curl_off_t variable to receive the number of seconds the
|
|
HTTP server suggests the client should wait until the next request is
|
|
issued. The information from the "Retry-After:" header.
|
|
|
|
While the HTTP header might contain a fixed date string, the
|
|
CURLINFO_RETRY_AFTER(3) always returns the number of seconds to wait -
|
|
or zero if there was no header or the header could not be parsed.
|
|
|
|
# DEFAULT
|
|
|
|
Returns zero delay if there was no header.
|
|
|
|

CURLcode res;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
