mov dword ptr [edx],0xAh ; *(pPtrArray[0])=10; The next logical step is to understand why the access violation occurred. Because we are trying to write to a memory location that equates to the first element in our array, the access violation might be because the memory being written...
--Sorting in linear time. 5 Heaps • Data structure indexed by integers 1, 2, …, n. • Each element supports the operation PARENT, LEFT, RIGHT. • Easily implemented using an array with PARENT(i) = , LEFT(i) = 2i, and RIGHT(i) = 2i + 1. 2 / i • max heap A[...
Node Structure • Child Pointer to first node of children list. • Left and Right Sibling Used for doubly linked linked list (not circular) of siblings. Left pointer of first node is to parent. x is first node in list iff x.left.child = x. ...

Vectored exception handling was introduced in windows XP and stores exception registration structures on the heap, unlike traditional frame exception handling such as SEH that stores its structure on the stack. This type of exception is called before any other frame based exception handling. The follo...
Below is a detailed table containing the structure of the segment meta data. For simplicity, we will start the address range at 0x00480000. The important information in a segment is the first chunk. This information alone can be used to 'walk' the segment, as you can display the chunk an...
