The curldown conversion accidentally replaced daniel@haxx.se with just daniel.se. This reverts back to the proper email address in the curldown docs as well as in a few other stray places where it was incorrect (while unrelated to curldown).

# NAME
|
|
|
|
CURLINFO_XFER_ID - get the ID of a transfer
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_XFER_ID,
|
|
curl_off_t *xfer_id);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a pointer to a *curl_off_t* to receive the identifier of the
|
|
current/last transfer done with the handle. Stores -1 if no transfer
|
|
has been started yet for the handle.
|
|
|
|
The transfer id is unique among all transfers performed using the same
|
|
connection cache. This is implicitly the case for all transfers in the
|
|
same multi handle.
