Thread
The #GThread struct represents a running thread. This struct is returned by g_thread_new() or g_thread_try_new(). You can obtain the #GThread struct representing the current thread by calling g_thread_self().
GThread is refcounted, see g_thread_ref() and g_thread_unref(). The thread represented by it holds a reference while it is running, and g_thread_join() consumes the reference that it is given, so it is normally not necessary to manage GThread references explicitly.
The structure is opaque -- none of its fields may be directly accessed.
