refSink

Increase the reference count of @object, and possibly remove the floating-ref reference, if @object has a floating reference.

In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

Since GLib 2.56, the type of @object will be propagated to the return type under the same conditions as for g_object_ref().
