Need some help.
I think?(scarry moment)? that I need to create more that one instance of a
dll.

1. Can this be done?
2. Is my sample even close?



"""gm_class  quick wrapper of dll functions"""

import windll
import time

class test:

    def __init__(self):
        self.gm=windll.module('GM4S32')

    def load_bde(self, SysDir='c:\\program files\\goldmine',
          GoldDir='c:\\program files\\goldmine\\gmbase',
          CommonDir='c:\\program files\\goldmine\\demo',
          User='PERACLES',
          Password=''):
        start=time.time()
        (SysDir, GoldDir, CommonDir,
         User, Password)=map(windll.cstring,(SysDir, GoldDir, CommonDir,
            User, Password))
        return (self.gm.GMW_LoadBDE(SysDir, GoldDir, CommonDir, User,
Password), "Startup Time: " + str(time.time()-start))

    def unload_bde(self):
        return self.gm.GMW_UnloadBDE()
