curl_multi_info_read - read multi stack informationals
|
|
|
|
|
|
</PRE>
|
|
<H2>SYNOPSIS</H2><PRE>
|
|
#include <curl/curl.h>
|
|
|
|
CURLMsg *curl_multi_info_read( CURLM *multi_handle,
|
|
int *msgs_in_queue);
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
Ask the multi handle if there are any messages/informa-
|
|
tionals from the individual transfers. Messages may
|
|
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 NULL is returned as a signal that there
|
|
is no more to get at this point. The integer pointed to
|
|
with <I>msgs</I><B>_</B><I>in</I><B>_</B><I>queue</I> 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):
|
|
|
|
struct CURLMsg {
|
|
CURLMSG msg; /* what this message means */
|
|
CURL *easy_handle; /* the handle it concerns */
|
|
union {
|
|
void *whatever; /* message-specific data */
|
|
CURLcode result; /* return code for transfer */
|
|
} data;
|
|
};
|
|
|
|
|
|
</PRE>
|
|
<H2>RETURN VALUE</H2><PRE>
|
|
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.
