How to code text file IO in DLL, unmanaged

[Progster]

I'd like to write a DLL in C++ which does text file IO. I plan to be
using the VS .Net Dev environment, but I want the DLL to work without
..Net runtime on the machine.

If I understand this right, that means I want my DLL to be compiled as
"unmanaged" code.

I would really appreciate a simple example or any tips on how to do
this, the correct IO classes to use, etc.

You can also use stdio.h, fopen, fread, fwrite, fprintf, fclose etc.
