Thanks Bob for the explanation.

If I have struct; say 'foo',

struct foo
{
     int* ptr1; //to be allocated by author of the struct using malloc
     int* ptr2; //to be allocated by author of the struct using malloc
    void*ptr3; // to be allocated by user of struct .i.e. client  using say malloc (not new operator)
}

1. Allocate foo: foo* f = (foo*)malloc(sizeof(foo));
2. Free foo: free(f);-> Will this not free memory pointed by ptr3 which is allocated and owned by user ?

Yes, it should. It will not do anything regarding allocations in ptr1 or ptr2 though.

C language provides hardly any automatic behavior other than to call atexit() handlers when the program calls exit() (or returns from main) and release the program's address space.
