LIB_FOUNDATION_LIBRARY or NeXT_PDO?

[Banlu Kemiyatorn]

Hi,
I have a question relate to XGServerEvent.m in method 
setupRunLoopInputSourcesForMode:
I don't understand what is the different between LIB_FOUNDATION_LIBRARY 
and NeXT_PDO.
Right now I am using the same way defined in NeXT_PDO but still 
wondering if the
way defined in LIB_FOUNDATION_LIBRARY is possibly more elegant since it 
will get
receivedEvent:type:extra:forMode: directly from the NSRunLoop.
What's NeXT_PDO? (Like if that make any sense for portable purpose, do 
you think it will affect
the portability of a window manager?) And why can't I see any 
description for
receivedEvent:type:extra:forMode: on apple.com but some sort of 
preparations that to be
described later on gnustep.org? Is this an undocumented feature?
Best regards,
]d
