minus-squaretunetardis@lemmy.calinkfedilinkarrow-up1·6 months agoFair, 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?
minus-squaremox@lemmy.sdf.orglinkfedilinkarrow-up1·6 months agoIn 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.)
minus-squareneo@lemy.lollinkfedilinkarrow-up0·6 months agoSo, when I want the void to point back at me, do I have to loop over void* or over NULL? And how many iterations?
