typedef struct ex * EXP;
void main(void)
{
int x=10;
struct test t2;
TESTP t1=(struct test *)malloc(sizeof(struct test));
EXP e1=(EXP)malloc(sizeof(struct ex));
(e1->testpp)=&t1;
t1->p=&x;
printf("%d\n",**(e1->testpp));
}
I would like to trace back to value stored at pointer p(i.e., 10), by using e1. is that possible to trace that? This code edited accidentally, i am not sure this will work. if it works please show me how can i trace back to value in 'p' using 'e1'.
You want to be able to dereference a chain starting with e1 getting to p eventually.
Here is how you do that:
printf("%d\n",*((*(e1->testpp))->p));
