CURLMOPT_MAXCONNECTS(3)	   Library Functions Manual    CURLMOPT_MAXCONNECTS(3)

NAME
       CURLMOPT_MAXCONNECTS - size of connection cache

SYNOPSIS
       #include	<curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS,	long max);

DESCRIPTION
       Pass  a long indicating the max,	the maximum amount of connections that
       libcurl may keep	alive in its connection	cache after  use.  By  default
       libcurl	enlarges  the size for each added easy handle to make it fit 4
       times the number	of added easy handles.

       By setting this option, you prevent the cache size from growing	beyond
       the limit set by	you.

       When  the  cache	 is full, curl closes the oldest connection present in
       the cache to prevent the	number of connections from increasing.

       This option is for the multi handle's use only, when using the easy in-
       terface you should instead use the CURLOPT_MAXCONNECTS(3) option.

       See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of	active
       connections.

       Changing	this value when	there are transfers in progress	 is  possible,
       and the new value is then used the next time checks are performed. Low-
       ering  the  value  does	not close down any active transfers, it	simply
       does not	allow new ones to get made.

DEFAULT
       See DESCRIPTION

PROTOCOLS
       This functionality affects all supported	protocols

EXAMPLE
       int main(void)
       {
	 CURLM *m = curl_multi_init();
	 /* only keep 10 connections in	the cache */
	 curl_multi_setopt(m, CURLMOPT_MAXCONNECTS, 10L);
       }

AVAILABILITY
       Added in	curl 7.16.3

RETURN VALUE
       curl_multi_setopt(3) returns a CURLMcode	indicating success or error.

       CURLM_OK	(0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
