Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# 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.

CURL *curl = curl_easy_init();

|
|
CURLcode res;
|
|
curl_off_t start;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
res = curl_easy_perform(curl);
|
|
if(CURLE_OK == res) {
|
|
res = curl_easy_getinfo(curl, CURLINFO_STARTTRANSFER_TIME_T, &start);
|
|
if(CURLE_OK == res) {
|
|
printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", start / 1000000,
|
|
(long)(start % 1000000));
