NAME
       curl_multi_perform - add an easy handle to a multi session

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode curl_multi_perform(CURLM *multi_handle, int *running_handles);

DESCRIPTION
       When  the  app  thinks there's data available for the multi_handle, it should call this function to read/write whatever there is to read or
       write right now. curl_multi_perform() returns as soon as the reads/writes are done. This function does not require that there  actually	is
       any  data  available for reading or that data can be written, it can be called just in case. It will write the number of handles that still
       transfer data in the second argument's integer-pointer.

RETURN VALUE
       CURLMcode type, general libcurl multi interface error code.

       NOTE that this only returns errors etc regarding the whole multi stack. There might still have occurred problems on invidual transfers even
       when this function returns OK.

TYPICAL USAGE
       Most  application  will	use curl_multi_fdset to get the multi_handle's file descriptors, then it'll wait for action on them using select()
       and as soon as one or more of them are ready, curl_multi_perform gets called.
