Object
This class represents libcurl multi.
Create a new multi. Initialize curl in case it didn't happen before.
@example Create a new Multi.
Multi.new
@param [ Hash ] options The options.
@option options :socketdata [String]
Pass a pointer to whatever you want passed to the curl_socket_callback's forth argument, the userp pointer. This is not used by libcurl but only passed-thru as-is. Set the callback pointer with CURLMOPT_SOCKETFUNCTION.
@option options :pipelining [Boolean]
Pass a long set to 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. (Added in 7.16.0)
@option options :timerfunction [Proc]
Pass a pointer to a function matching the curl_multi_timer_callback prototype. This function will then be called when the timeout value changes. The timeout value is at what latest time the application should call one of the "performing" functions of the multi interface (curl_multi_socket_action(3) and curl_multi_perform(3)) - to allow libcurl to keep timeouts and retries etc to work. A timeout value of -1 means that there is no timeout at all, and 0 means that the timeout is already reached. Libcurl attempts to limit calling this only when the fixed future timeout time actually changes. See also CURLMOPT_TIMERDATA. This callback can be used instead of, or in addition to, curl_multi_timeout(3). (Added in 7.16.0)
@option options :timerdata [String]
Pass a pointer to whatever you want passed to the curl_multi_timer_callback's third argument, the userp pointer. This is not used by libcurl but only passed-thru as-is. Set the callback pointer with CURLMOPT_TIMERFUNCTION. (Added in 7.16.0)
@option options :maxconnects [Integer]
Pass a long. The set number will be used as the maximum amount of simultaneously open connections that libcurl may cache. Default is 10, and libcurl will enlarge the size for each added easy handle to make it fit 4 times the number of added easy handles. By setting this option, you can prevent the cache size from growing beyond the limit set by you. When the cache is full, curl closes the oldest one in the cache to prevent the number of open connections from increasing. This option is for the multi handle's use only, when using the easy interface you should instead use the CURLOPT_MAXCONNECTS option. (Added in 7.16.3)
@return [ Multi ] The new multi.
