ref_thread_default
Description:
Gets the thread-default MainContext for this thread, as with
get_thread_default, but also adds a reference to it with
g_main_context_ref
.
In addition, unlike get_thread_default, if the thread-default context is the global-default context, this will return that MainContext (with a ref added to it) rather than returning null.
Returns:
the thread-default MainContext. Unref with |
