.SH NAME
CURLINFO_RETRY_AFTER \- returns the Retry\-After retry delay
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RETRY_AFTER,
                           curl_off_t *retry);
.fi
.SH 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
\fICURLINFO_RETRY_AFTER(3)\fP always returns the number of seconds to wait \-
or zero if there was no header or the header could not be parsed.

This option used to return a negative wait time if the server provided a date
in the past. Since 8.12.0, a negative wait time is returned as zero. In any
case we recommend checking that the wait time is within an acceptable range for
your circumstance.
.SH DEFAULT
Zero if there was no header.
.SH PROTOCOLS
This functionality affects all supported protocols

int main(void)
