# NAME
|
||
|
|
|
||
|
|
CURLINFO_STARTTRANSFER_TIME_T - get the time until the first byte is received
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_STARTTRANSFER_TIME_T,
|
||
|
|
curl_off_t *timep);
|
||
|
|
~~~
|

|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a pointer to a curl_off_t to receive the time, in microseconds,
|
||
|
|
it took from the
|
||
|
|
start until the first byte is received by libcurl. This includes
|
||
|
|
CURLINFO_PRETRANSFER_TIME_T(3) and also the time the server needs to
|
||
|
|
calculate the result.
|
||
|
|
|
||
|
|
When a redirect is followed, the time from each request is added together.
|
||
|
|
|
||
|
|
See also the TIMES overview in the curl_easy_getinfo(3) man page.
