curl_multi_info_read — Get information about the current transfers
Ask the multi handle if there are any messages or information from the individual transfers. Messages may include information such as an error code from the transfer or just the fact that a transfer is completed.
Repeated calls to this function will return a new result each time, until a false is returned
as a signal that there is no more to get at this point. The integer pointed to with
queued_messages will contain the number of remaining messages after this
function was called.
The data the returned resource points to will not survive calling curl_multi_remove_handle().
mhМультидескриптор cURL, якого повертає curl_multi_init().
queued_messagesNumber of messages that are still in the queue
On success, returns an associative array for the message, false on failure.
| Key: | Value: |
|---|---|
msg |
The CURLMSG_DONE constant. Other return values
are currently not available. |
result |
One of the CURLE_* constants. If everything is
OK, the CURLE_OK will be the result. |
handle |
Resource of type curl indicates the handle which it concerns. |
