inp, outp function with Win32?

Dear Experts:

I'm trying to convert old 16bit windows program to 32bit windows one. I used this program to control ADC/DAC cards.
So there are lots of inp and outp function to read and write
to ports to control these interface cards.
But when I tried to convert this program to 32bit one using
C language(Borlandc++4.5 , 5.0 but not C++), I got error messages that in 32bit mode, there are no inp and outp function.
What should I do to remedy this problem?
Is there any compatible function or other way to use this
functions in 32bit programming?
Thank you in advance.

Under win32, you can not directly access the port in applications.  So you have to write a vxd (device driver) for your task.  You can get microsoft DDK for detail as how to write a vxd.
