32 Pass a long. The set \fIamount\fP will be the maximum number of simultaneously
33 open persistent connections that libcurl may cache in the pool associated with
34 this handle. The default is 5, and there isn't much point in changing this
35 value unless you are perfectly aware of how this works and changes libcurl's
36 behaviour. This concerns connections using any of the protocols that support
37 persistent connections.
39 When reaching the maximum limit, curl closes the oldest one in the cache to
40 prevent increasing the number of open connections.
42 If you already have performed transfers with this curl handle, setting a
43 smaller \fICURLOPT_MAXCONNECTS(3)\fP than before may cause open connections to
44 get closed unnecessarily.
46 If you add this easy handle to a multi handle, this setting is not
47 acknowledged, and you must instead use \fIcurl_multi_setopt(3)\fP and the
48 \fICURLMOPT_MAXCONNECTS(3)\fP option.
55 CURL *curl = curl_easy_init();
58 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
