Handling .dll file using ruby in windows XP

[Chandra Sekhar]

Hi,

I am new to Ruby. I want to use a dll with RUBY to change/modify the
frequency value in a signal generator.

Is it possible to open dll file in ruby to read/write the value in it?


Thanks,
Chandra

While you can alter the contents of a binary file (DLL), I presume is
not what you want as will render the DLL useless afterwards.

Please read the API documentation of the DLL you want to use and take
a look to Ruby FFI interface for writing down a module that interfaces
it.
