Pointers are variables that contain addresses. By dereferencing a pointer in the command interface, you can print the value at the address pointed to by the pointer. In C and C++ programs, variables containing a pointer are dereferenced using the * operator. The following example shows how to dereference a pointer in C++ programs:
(idb) whatis newNode
class IntNode* newNode
(idb) print newNode
0x805e5f8
(idb) print *newNode
class IntNode {
_data = 1;
_nextNode = 0x0; // class Node
}
