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. For each new
33 session to a host, libcurl will open a new connection up to the limit set by
34 \fICURLMOPT_MAX_HOST_CONNECTIONS(3)\fP. When the limit is reached, the
35 sessions will be pending until a connection becomes available. If
36 \fICURLMOPT_PIPELINING(3)\fP is enabled, libcurl will try to pipeline if the
37 host is capable of it.
39 The default \fBmax\fP value is 0, unlimited. However, for backwards
40 compatibility, setting it to 0 when \fICURLMOPT_PIPELINING(3)\fP is 1 will not
41 be treated as unlimited. Instead it will open only 1 connection and try to
