Q: 

Box-and-circle diagram of a double pointer?

Does anyone have a link to a box-and-circle diagram of a double pointer?

+2  A: 

Check out

http://www.mattababy.org/~belmonte/Teaching/CCC/CCC/transparent_figure5.gif

from this crash course in C. It shows a "pointer to a pointer" diagram in terms of a two-dimensional array.

If you're looking for something more basic:

  ______        ____       _____
 /      \      /    \     |     |
| int**  |--->| int* |--->| int |
 \______/      \____/     |_____|
