CURLOPT_MAXCONNECTS(3) curl_easy_setopt options CURLOPT_MAXCONNECTS(3) NAME CURLOPT_MAXCONNECTS - maximum connection cache size SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount); DESCRIPTION Pass a long. The set amount will be the maximum number of simultane- ously 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 and changes libcurl's behavior. 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 PROTOCOLS Most EXAMPLE 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); } AVAILABILITY Always RETURN VALUE Returns CURLE_OK ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | web/curl | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO CURLMOPT_MAXCONNECTS(3), CURLOPT_MAXREDIRS(3), NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
