Cast void pointer to integer array

Question

I have a problem where I have a pointer to an area in memory. I would like to use this pointer to create an integer array.

Essentially this is what I have, a pointer

Answer 1

You can cast the pointer to unsigned int (*)[150]. It can then be used as if it is a 2D array ("as if", since behavior of sizeof is different).

unsigned int (*array)[150] = (unsigned int (*)[150]) ptr;
