[petsc-users] Checking if a vector is a localvector of a given DMDA

[Phil Tooley]

Hi all,

Given a vector I know I can get an associated DM (if there is one) by
calling VecGetDM, but I need to also be able to check that

a) the vector is the localvector of that DM rather than the global

b) the DM is a DMDA rather than some other subclass

I can't immediately see routines that do what I need, but I am likely
missing something obvious. Is there a way to achieve the above?

Thanks

Phil
