filter

Description:

If func returns REMOVE, the session will be set to the expired state and removed from this.

If func returns KEEP, the session will remain in this.

If func returns REF, the session will remain in this but will also be added with an additional ref to the result GList of this function..

When func is null, REF will be assumed for all sessions.

Parameters:

this	a SessionPool
func	a callback
user_data	user data passed to `func`

Returns:

a GList with all sessions for which func returned REF . After usage, each element in the GList should be unreffed before the list is freed.
