The name defaults to
The source name should describe in a human-readable way what the source does. For example, "X11 event queue" or "GTK repaint idle handler" or whatever it is.
It is permitted to call this function multiple times, but is not recommended due to the potential performance impact. For example, one could change the name in the "check" function of a SourceFuncs to include details like the event type in the source name.
Use caution if changing the name while another thread may be accessing it with get_name; that function does not copy the value, and changing the value will free it while the other thread may be attempting to use it.
