Add the two following functions to the socket module:

def get_inheritable(sock):
    if os.name == 'nt':
        return os.get_handle_inheritable(sock.fileno())
        return os.get_inheritable(sock.fileno())

def set_inheritable(sock, inheritable):
    if os.name == 'nt':
        os.set_handle_inheritable(sock.fileno(), inheritable)
        os.set_inheritable(sock.fileno(), inheritable)

Usage: socket.get_inheritable(sock) and socket.set_inheritable(sock, True)

> Or add 2 methods to the socket class?

Add the two following methods to the socket class:

    def get_inheritable(self):
        if os.name == 'nt':
            return os.get_handle_inheritable(self.fileno())
            return os.get_inheritable(self.fileno())

    def set_inheritable(self, inheritable):
        if os.name == 'nt':
            os.set_handle_inheritable(self.fileno(), inheritable)
            os.set_inheritable(self.fileno(), inheritable)

Usage: s.get_inheritable() and sock.set_inheritable(True)
