I was wondering whether it is possible to do something like this:
unsigned int address = 0x0001FBDC; // Random address :P
int value = *address; // Dereference of address
Meaning, is it possible to get the value of a particular address in memory ?
Thanks
You can and should write it like this:
#include <cstdint>
uintptr_t p = 0x0001FBDC;
int value = *reinterpret_cast<int *>(p);
Note that unless there is some guarantee that p
points to an integer, this is undefined behaviour. A standard operating system will kill your process if you try to access an address that it didn't expect you to address. However, this may be a common pattern in free-standing programs.
(Earlier versions of C++ should say #include <stdint.h>
and intptr_t
.)
