Actually
void*
just points to anything, with no regard to the type of that thing. Pointing to the void is more accurately described byNULL

int*
which is a memory location of an int10 0 Reply

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?7 0 ReplyFor the void to point back at you just dereference the NULL pointer
7 0 Replyas 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.)
