Hi Srini,
The idea is that you don't explicitly pass any arguments to the function call
(the only argument being the MSI handle that get's set by the installer),
instead they are passed by a process of the installer setting up the necessary
properties before the custom action is executed. Then within the DLL's function
you make calls to MsiGetProperty() to get the "arguments" and do your
processing. In a similar way, if you need some OUT arguments you use
MsiSetProperty.
If you google for MsiGetProperty you will find many examples (some not wix
specific, but it does not matter), but here are some starting points for you:

That should get you started, plus it seems there are some threads in the
archive for this mailing list, so you should be able to find some tips
searching through that as well.
Good luck,
Ian.

Subject: Re: [WiX-users] How to call a .dll from wix with arguments?
Does this mean I have to use only one argument by combining those two
arguments?. You also said that "Your custom action will have to read any other
information it needs from the install database using e.g. MsiGetProperty."
What is meant by that?. Can you elaborate?.
Any good examples?. Thank you very much.
