report_new_error

Description:

[ PrintfFormat ]
[ Version ( since = "2.36" ) ]
public static void report_new_error (Object? source_object, TaskReadyCallback callback, void* source_tag, Quark domain, int code, string format, ...)

Creates a Task and then immediately calls return_new_error on it.

Use this in the wrapper function of an asynchronous method when you want to avoid even calling the virtual method. You can then use is_tagged in the finish method wrapper to check if the result there is tagged as having been created by the wrapper method, and deal with it appropriately if so.

Parameters:

source_object	the Object that owns this task, or null.
callback	a TaskReadyCallback.
source_tag	an opaque pointer indicating the source of this task
domain	a Quark.
code	an error code.
format	a string with format characters.
...	a list of values to insert into `format`.
callback_data	user data passed to `callback`.
