Why I cannot do reqPositions()?

[hasakura511]

when i do: tws.reqPositions()

it gives me this error: AttributeError: 'EPosixClientSocket' object has no attribute 'reqPositions'

When i checked the swigibpy.py reqPositions is defined in EClient and EClientSocketBase

def reqPositions(self):
    """reqPositions(EClientSocketBase self)"""
    return _swigibpy.EClientSocketBase_reqPositions(self)

when I do dir(EPosixClientSocket) its not there. Can someone please help me understand why and how to load it?

Thanks.
