This function is currently not documented; only its argument list is available.
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, the value is a bitmask, and you can also pass 2 to try to multiplex the new transfer over an existing HTTP/2 connection if possible. Passing 3 instructs cURL to ask for pipelining and multiplexing independently of each other. As of cURL 7.62.0, setting the pipelining bit has no effect. 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. By default the size will be enlarged to fit four times the number of handles added via curl_multi_add_handle. When the cache is full, curl closes the oldest one in the cache to prevent the number of open connections from increasing. CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE Pass a number that specifies the chunk length threshold for pipelining in bytes. CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE Pass a number that specifies the size threshold for pipelining penalty in bytes. CURLMOPT_MAX_HOST_CONNECTIONS Pass a number that specifies the maximum number of connections to a single host. CURLMOPT_MAX_PIPELINE_LENGTH Pass a number that specifies the maximum number of requests in a pipeline. CURLMOPT_MAX_TOTAL_CONNECTIONS Pass a number that specifies the maximum number of simultaneously open connections. CURLMOPT_PUSHFUNCTION Pass a callable that will be registered to handle server pushes and should have the following signature:pushfunction(
The parent cURL handle (the request the client made).
A new cURL handle for the pushed request.
The push promise headers.
Returns true on success or false on failure.
|multi_handle expects a CurlMultiHandle instance now; previously, a resource was expected.
