25 CURLMOPT_MAX_HOST_CONNECTIONS \- set max number of connections to a single host
27 #include <curl/curl.h>
29 CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_HOST_CONNECTIONS, long max);
31 Pass a long to indicate \fBmax\fP. The set number will be used as the maximum
32 amount of simultaneously open connections to a single host (a host being the
33 same as a host name + port number pair). For each new session to a host,
34 libcurl will open a new connection up to the limit set by
35 \fICURLMOPT_MAX_HOST_CONNECTIONS(3)\fP. When the limit is reached, the
36 sessions will be pending until a connection becomes available. If
37 \fICURLMOPT_PIPELINING(3)\fP is enabled, libcurl will try to pipeline if the
38 host is capable of it.
40 The default \fBmax\fP value is 0, unlimited. However, for backwards
41 compatibility, setting it to 0 when \fICURLMOPT_PIPELINING(3)\fP is 1 will not
42 be treated as unlimited. Instead it will open only 1 connection and try to
45 This set limit is also used for proxy connections, and then the proxy is
46 considered to be the host for which this limit counts.
56 Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not.
