In C and C++, void* is for data pointers but it works (by accident?) for function pointers on all popular platforms.
For 16 bit programs, function pointers can be different sizes from data pointers. But D doesn't support 16 bit programming, and I know of no 32+ bit platform that does this.
It is possible to put the x86 in a mode with 48 bit function pointers, but so far as I know no C compiler allows that anyway.
Does D have anything to say about this topic?
I'd say they were the same size. If, by some quirk, someone wants to port D to a platform where this was not true, they could certainly get it to work, but I don't think it is practical to burden the other 99.99999% with worrying about that.
