Actually
void*
just points to anything, with no regard to the type of that thing. Pointing to the void is more accurately described byNULL
pointer. 98ReplyFair, though I guess my interpretation was that
void*
is kind of like a black hole in that anything can fall into it in an unsettling way that loses information about what it was? 38ReplyIt erases the type of what your pointing at. All you have is a memory location, in contrast to
int*
which is a memory location of an int 10Reply

27ReplyBut we need dynamic types!

So, when I want the void to point back at me, do I have to loop over void* or over NULL?
And how many iterations? 7ReplyFor the void to point back at you just dereference the NULL pointer
7Replyas many iterations as it takes
void* x = &x; char* ptr = (char*)&x; while (1) { printf("%d\n", (unsigned int)*ptr); ptr--; }

In other words,
void
refers to the typing of the pointer, not a particular value that might be present at its target.(But I can see how someone might find it confusing.)

13ReplyThere are no ints in the void, only... death...
5ReplyFor God sake, be consistent. It's either
int*, int**, void*
orint *, int **, void *
