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
|
|
|
|
CURLOPT_MAXCONNECTS - maximum connection cache size
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. The set *amount* is the maximum number of simultaneously open
|
|
persistent connections that libcurl may cache in the pool associated with this
|
|
handle. The default is 5, and there is not much point in changing this value
|
|
unless you are perfectly aware of how this works. This concerns connections
|
|
using any of the protocols that support persistent connections.
|
|
|
|
When reaching the maximum limit, curl closes the oldest one in the cache to
|
|
prevent increasing the number of open connections.
|
|
|
|
If you already have performed transfers with this curl handle, setting a
|
|
smaller CURLOPT_MAXCONNECTS(3) than before may cause open connections to
|
|
get closed unnecessarily.
|
|
|
|
If you add this easy handle to a multi handle, this setting is not
|
|
acknowledged, and you must instead use curl_multi_setopt(3) and the
|
|
CURLMOPT_MAXCONNECTS(3) option.
|
|
|
|
# DEFAULT
|
|
|
|
5
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode ret;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
/* limit the connection cache for this handle to no more than 3 */
|
|
curl_easy_setopt(curl, CURLOPT_MAXCONNECTS, 3L);
|
|
ret = curl_easy_perform(curl);
|
|
}
|
|
}
