.SH DESCRIPTION
|
2021-11-01 20:43:11 +08:00
|
|
|
Pass a pointer to a curl_off_t to receive the time, in microseconds, it took
|
|
|
|
|
from the start until the SSL/SSH connect/handshake to the remote host was
|
2021-11-26 15:46:59 +08:00
|
|
|
completed. This time is most often close to the
|
2021-11-01 20:43:11 +08:00
|
|
|
\fICURLINFO_PRETRANSFER_TIME_T(3)\fP time, except for cases such as HTTP
|
|
|
|
|
pipelining where the pretransfer time can be delayed due to waits in line for
|
|
|
|
|
the pipeline and more.

|
|
|
|
2019-08-27 05:36:39 +08:00
|
|
|
When a redirect is followed, the time from each request is added together.
