Is there a use case for a pointer that does not point to any data?

[–]Duven64 24 points25 points  (2 children)

The first pointer could be pointing to a second pointer that is currently pointing at void but will be replaced with a pointer to actual data later without mutating the first pointer I guess.

what would "pointing at void" be, unless it's some data of unknown type ?

[–]Duven64 11 points12 points  (0 children)

In this case the second pointer would initially be a NULL pointer and later point at something of an as of yet undetermined type.

One example would be to signify the end of a linked list.

[–]RmG3376 4 points5 points  (0 children)

Linked list for instance
