is that the reason for plvec2? Because Fortran, ever since it supported user-defined functions, so at least from FORTRAN IV onwards, has supported passing function names as arguments. There is an important limitation vis-a-vis the _data_ that you can pass - that is: no equivalent to (void *) types, but function names are no problem at all!
