Using this .gdbinit macro:
define plist
set var $plist_iter=$arg0
while ($plist_iter)
if $argc==1
print *$plist_iter
else
if $argc==2
print $plist_iter->$arg1
else
print$arg2 $plist_iter->$arg1
end
end
set var $plist_iter=$plist_iter->next
end
end
document plist
List dumper iterating by `->next':
plist <head pointer> [<data field to display>] [/<format>]
end
