NAME

6       CURLINFO_PRETRANSFER_TIME_T  -  get  the  time  until the file transfer
7       start
8

SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode curl_easy_getinfo(CURL  *handle,  CURLINFO_PRETRANSFER_TIME_T,
13       curl_off_t *timep);
14

DESCRIPTION

16       Pass a pointer to a curl_off_t to receive the time, in microseconds, it
17       took from the start until the file transfer is  just  about  to  begin.
18       This  includes all pre-transfer commands and negotiations that are spe‐
19       cific to the particular protocol(s) involved. It does not  involve  the
20       sending of the protocol- specific request that triggers a transfer.
