NAME
       curl_multi_info_read - read multi stack informationals

SYNOPSIS
       #include <curl/curl.h>

       CURLMsg *curl_multi_info_read( CURLM *multi_handle,
                                      int *msgs_in_queue);

DESCRIPTION
       Ask  the  multi  handle if there's any messages/informationals from the
       individual transfers. Messages include informationals such as an  error
       code  from  the transfer or just the fact that a transfer is completed.
       More details on these should be written down as well.

       Repeated calls to this function will return a  new  struct  each  time,
       until a special "end of msgs" struct is returned as a signal that there
       is no  more  to  get  at  this  point.  The  integer  pointed  to  with
       msgs_in_queue  will contain the number of remaining messages after this
       function was called.

       The data the returned  pointer  points  to  will  not  survive  calling
       curl_multi_cleanup().

       The  'CURLMsg' struct is very simple and only contain very basic infor-
       mations.  If more involved information is wanted, the particular  "easy
       handle"  in  present  in that struct and can thus be used in subsequent
       regular curl_easy_getinfo() calls (or similar).

RETURN VALUE
       A pointer to a filled-in struct, or NULL if it failed  or  ran  out  of
       structs. It also writes the number of messages left in the queue (after
       this read) in the integer the second argument points to.
