3D array initialization in struct

[colinexl]

Hi All,

I have a struct like this:

struct Cache
{
    int *** cache;
};

and in my main() I have

int cache[8][1][1];
struct Cache sim;

sim.cache = (int ***)cache;

I want to set the int *** cache to the same 3D array called "cache" in main. However, when I try something like "sim.cache[1][1][1] = 0;", I get a segfault.

I don't know if I'm initializing the 3D array in my struct correctly. Can someone confirm please?

Thanks,
Colin

Pointer != array, etc.

Have you tried something like this?

struct Cache
{
    int (*cache)[1][1];
};

int cache[8][1][1] =
{
   { {1} },
   { {2} },
   { {3} },
   { {4} },
   { {5} },
   { {6} },
   { {7} },
   { {8} },
};

int main(void)
{
   struct Cache sim = {cache};
