One of the CURLMOPT_* constants.


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. As of cURL 7.43.0 you can also pass 2 to try to multiplex the new transfer over an existing HTTP/2 connection if possible. Instead of integer literals, you can also use the CURLPIPE_* constants if available.
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.

Return Values

Returns TRUE on success or FALSE on failure.
