in c and c++, the asterisk operator is used to declare and manipulate pointers. for example, int *ptr declares a pointer to an integer named ptr. what is pointer arithmetic in programming, and how is the asteris
This returns a pointer to an array of IMFActivate COM interfaces, not the most friendly format for interop with .NET. You can walk through the array with some pointer arithmetic and using Marshal.GetObjectForIUnknown for each IMFActivate. You need to remember to call Marshal.FreeCoTaskMem on ...
The original data in the buffer includes the exploited function's return pointer -- the address to which the process should go next. However, the attacker can set new values to point to an address of their choosing. The attacker usually sets the new values to a location where theexploitpayl...

Let us see an example code where I am implementing the call-back function using the function pointer. #include<stdio.h> //Create a type using typedef typedefint(*pfCallback)(int,int); /* API to perform arithmetic operation */ intarithmatic_operation(pfCallback pfun,int data1, int data2...
(char*)ptr + 1), it will advance the pointer 1 byte, because a "char" is 1 byte. The code ((void*)ptr + 1) does not work, because the compiler has no idea what size "void" is, and therefore doesn't know how many bytes to add. This is why you got Error 1 C2036, from ...
