- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

NAME
CURLINFO_NUM_CONNECTS - get number of created connections
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump);
DESCRIPTION
Pass a pointer to a long to receive how many new connections libcurl had to create to achieve the previous transfer (only the successful connects are counted). Combined with CURLINFO_REDIRECT_COUNT(3) you are able to know how many times libcurl successfully reused existing connection(s) or not. See the connection options of curl_easy_setopt(3) to see how libcurl tries to make persistent connections to save time.

EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
res = curl_easy_perform(curl);
if(res == CURLE_OK) {
long connects;
res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects);
if(!res)
printf("It needed %ld connects\n", connects);
}
curl_easy_cleanup(curl);
}
}

RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
