Anyway, so the question is: how do we write callback functions in FP/Haskell? Can someone provide a simple, but functional example?
What makes a callback different from any other kind of function? In Haskell, as in other functional programming languages, you're completely free to pass functions into other functions and store them in datastructures. Take a look at the 'callbacks' used in the HOpenGL examples. They're just ordinary functions: http://cvs.haskell.org/cgi-bin/cvsweb.cgi/fptools/libraries/GLUT/examples/RedBook/ -- Dan _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
