# NAME

CURLINFO_RETRY_AFTER - returns the Retry-After retry delay

# SYNOPSIS

~~~c
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RETRY_AFTER,
                           curl_off_t *retry);
~~~

# 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

Zero if there was no header.

    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      curl_off_t wait = 0;
