I want to access the data stored in the vec object directly without

I tried using something like p->hdr._ in a printf statement (where p
is a vector). I wish to know which element of the _p_Vec structure
stores the data.
I think it's impossible for a good reason (or at least highly discouraged).
Why don't you want to use a prescribed interface? It's really light-weight.
But don't forget to call VecRestoreArray after directly manipulating the
data.

Hey,
I am fairly new to PetSc. I was just curious as to how you can
directly access the data stored in a Petsc object, say a vector
without using VecGetValues().
I've gone through the header files, petscimpl.h and vecimpl.h
which contain the definitions of the PetscObject and Vec
structures. I cannot figure out which member of the struct holds
the Vector data entered using VecSet(). Also, I could not find the
definitions of the functions in VecOps. Could someone tell me
where I can find these function definitions?
Thank you :)
