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 ?

This is the situation inside TIFFClose(p)-> TIFFCleanup(p) -> TIFFFree(p)->free(p) where p is the TIFF* like foo* in the dummy example and thandle_t is like ptr3 above allocated by our code.

Thanks,
Upanita
