curl_multi_info_read(3) libcurl Manual curl_multi_info_read(3)
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 are any messages/informationals from the individual trans-
fers. 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 msgs_in_queue will contain the number of remaining messages after this function was
called.
When you fetch a message using this function, it is removed from the internal queue so
calling this function again will not return the same message again. It will instead return
new messages at each new invoke until the queue is emptied.
WARNING: The data the returned pointer points to will not survive calling
curl_multi_cleanup(3), curl_multi_remove_handle(3) or curl_easy_cleanup(3).
The 'CURLMsg' struct is very simple and only contain very basic information. 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(3) 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;
};
When msg is CURLMSG_DONE, the message identifies a transfer that is done, and then result
contains the return code for the easy handle that just completed.
At this point, there is no other msg types defined.
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 sec-
ond argument points to.
