Advanced Fortran 90: Callbacks with the Transfer Function
This post is not specific to the Mac, but there are probably many MR readers that have to use Fortran in some aspect of their work, so it certainly can’t hurt… Callbacks for Mac A few weeks ago I was lamenting the difficulty of implementing decent callback functionality in Fortran…
