Revised solution uses 'from_address' instead of '_ctypes._cast_addr'.
import ng27ext
import ctypes as c
class TypeA( c.Structure ):
_fields_= [
( 'a', c.c_int ),
( 'b', c.c_float )
]
def exposed( pobj1, pobj2 ):
obj1= TypeA.from_address( pobj1 )
obj2= TypeA.from_address( pobj2 )
print obj1.a, obj1.b
obj2.a= c.c_int( 60 )
obj2.b= c.c_float( 65.5 )
print obj2.a, obj2.b
print ng27ext.methA( exposed )
