curl_multi_info_read

Name: curl_multi_info_read()

Desc: Ask the multi handle if there's any messages/informationals from the individual transfers. Messages include informationals such as 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 data the returned pointer points to will not survive calling curl_multi_cleanup().

The 'CURLMsg' struct is meant to be very simple and only contain very basic informations. If more involved information is wanted, we will provide the particular "transfer handle" in that struct and that should/could/would be used in subsequent curl_easy_getinfo() calls (or similar). The point being that we must never expose complex structs to applications, as then we'll undoubtably get backwards compatibility problems in the future.

Return Value

Type: CURLMsg*

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.
