Function
GioAsyncReadyCallback
Declaration
void
(* GAsyncReadyCallback) (
GObject* source_object,
GAsyncResult* res,
gpointer data
)
Description
Type definition for a function that will be called back when an asynchronous
operation within GIO has been completed. GAsyncReadyCallback
callbacks from GTask are guaranteed to be invoked in a later
iteration of the
[thread-default main context][g-main-context-push-thread-default]
where the GTask was created. All other users of
GAsyncReadyCallback must likewise call it asynchronously in a
later iteration of the main context.
The asynchronous operation is guaranteed to have held a reference to
source_object from the time when the *_async() function was called, until
after this callback returns.
Parameters
