I would like to call a C-program from Mathematica. All the examples in
the MathLink tutorials (like AddTwo[i,j]) work like this: they are
called from Mathematica, are executed, send the result to Mathematica
and exit.

I would like a C-program to not exit after the execution, and keep the
memory of the previous inputs. Say, I want an external C-program, to
be called as AddToPreviousSum[x]. When it is first called, it returns
x. When it is called the second time AddToPreviousSum[y], it returns x
+y. When it is called the third time AddToPreviousSum[z], it returns x
+y+z, and so on.

How do I implement this in C using MathLink?
