arguments have to appear at the end of the list, which makes sense in
a way. If we want it to appear in the same position as the C API, then
I will have to use another mechanism. Nothing dramatic, only a bit
more code, as I will have to add alternative routines then. Let me
know what you think.

Let's use "another mechanism" which I assume is function overloading
(which I know is possible with Fortran 95).  For me it is quite
important to keep the same order of arguments in other languages as in
C, and function overloading should gives you the chance to do that.
