Hi Virgil,

first of all. I have never used the package. I just compile it for fun.
Typical I have a C program that runs to long in MathLink mode. The
C-program
write some files and a mathlink program read the binaries. This is
better
than to use the general routine. The general routine works fine if you
have
cross-platform binaries ( Cray T3D output) and you do some post
processing with
Mathematica.

In the windows directory. But there is a MathLink.ini file because
Matheamtica use MathLink.

You can only load it into the kernel. The Frontend and the notebook
interface
call the kernel and the kernel call your MathLink program. 
Install[] will also work.

Write a file/read a file ? Worte a small C program that create
a binary file with know data and try to read it with Mathematica ?
