mh

option

One of the CURLMOPT_* constants.

value

The value to be set on option.

value should be an int for the following values of the option parameter:

Option	Set `value` to
`CURLMOPT_PIPELINING`	Pass 1 to enable or 0 to disable. Enabling pipelining on a multi handle will make it attempt to perform HTTP Pipelining as far as possible for transfers using this handle. This means that if you add a second request that can use an already existing connection, the second request will be "piped" on the same connection rather than being executed in parallel.
`CURLMOPT_MAXCONNECTS`	Pass a number that will be used as the maximum amount of simultaneously open connections that libcurl may cache. Default is 10. When the cache is full, curl closes the oldest one in the cache to prevent the number of open connections from increasing.

Returns TRUE on success or FALSE on failure.
