I dont understand what is a pointer to a pointer if p is a pointer to a structure ( struct str* p
so p contain the adress of the structure using malloc but what does *p contain ?? what is the meaning of struct str **p; ??

struct str v, *p, **p;
p = &v;
pp = &p;
Here we have those relations :
*p ==**pp == v
pp == &p == &&v
p == *pp == &v

Simple
* Means VALUE AT
&Means ADDRESS OF
*P means the value which is stored in the variable.
&P means the address of that variable.
I think you got the answer
