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 information
als 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 num
ber 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).
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.
