i'm trying to share a struct like this
example:

typedef struct {
    int* a;
    int b;
    int c;
} ex;

between processes, the problem is that when I initialize 'a' with a malloc, it becomes private to the heap of the process that do this(or at least i think this is what happens). Is there any way to create a shared memory (with shmget, shmat) with this struct that works?

EDIT: I'm working on Linux.

EDIT: I have a process that initialize the buffer like this:

key_t key = ftok("gr", 'p');   
int mid = shmget(key, sizeof(ex), IPC_CREAT | 0666);    
ex* e = NULL;
status b_status = init(&e, 8); //init gives initial values to b c and allocate space for 'a' with a malloc
e = (ex*)shmat(mid, NULL, 0);

the other process attaches himself to the shared memory like this:

key_t key = ftok("gr", 'p');
int shmid = shmget(key, sizeof(ex), 0);
ex* e;
e = (ex*)shmat(shmid, NULL, 0);  

and later get an element from a, in this case that in position 1

int i = get_el(e, 1);
