Message: [QUOTE="Rufus V. Smith, post: 1713481"] Good One Malcolm! Almost made me wet my pants. I've been absent from the newsgroups for a time (unemployment can do that), but was following this thread with some uneasy interest. At first I thought, "of course function pointers aren't used only for callback functions." But after reading and thinking, I decided that ultimately, if that function pointer is every actually used it is effectively "calling back" to the function it points to. However, your fine example shows that if we use the function pointers only as pointers, there is no "calling", hence no "callback" happening. Which brings me back to one observation, though: function pointers are NEVER callback functions They are POINTERS TO callback functions. let me slip back into my teapot now. Rufus [/QUOTE]
