What is a parameter (void *)

Question

I recently saw a delegate method (which seems to work) and looks like this:

- (void) doSomethingWithThisPieceOfData: (void *) theData;

Then the delegate method distinguishes Data as:

- (void) doSomethingWithThisPieceOfData: (void *) theData {anObject * myObject; myObject = (anObject) theData; ....}

Why does this work, and is it good coding practice? Instead, I would use (id *) theData.

thank.

Answer 1

void * as a type indicates that any pointer can be passed, and that the code that receives it will distinguish it from any type that it considers appropriate.
