I am looking for a project which is converting c malloc/realloc to shared_ptr. During my Analysis, I found the issue

Can anyone provide me some input how to fix below issue

typedef boost::shared_ptr<Employee_t> srdpointer;

srdpointer ptr((Employee_t*)malloc(sizeof(Employee_t)),std::ptr_fun(free));

I need to pass the shared pointer which will allocate memory Pointed by the ptr. Something like this.

void allocateBlocks(int **ptr, int *cnt)
    {
        *ptr =
 (int*)malloc(sizeof(int) * 10);
        *cnt = 10;
        /*do something*/ 
    }

    int main()
    {
        int *p = NULL;
     
   int count = 0;
        allocateBlocks(&p, &count);
        /*do something*/

        free(p);
    }

How can I achieve the similar functionality using shared ptr as shown in above code
