curl_multi_info_read - read multi stack informationals
CURLMsg *curl_multi_info_read( CURLM *multi_handle,
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 informations. 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).
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 sec-
ond argument points to.
