Suministrado por el infalible Lagarto, era predecible pero me hace sonreír y eso es lo que realmente cuenta...
Empty your mind, be formless, shapeless — like a void pointer. If you cast
a void pointer into an integer, it becomes the integer. You cast a void
pointer into a struct it becomes the struct. You cast it into a char it
becomes the char. Now, void pointers can be dereferenced or they can be
null. Be a void pointer, my friend.
