[petsc-users] VecDeviceGetArray?

There does not seem to be a Read variant of VecGetArrayAndMemType.
I am getting an error:
[0]PETSC ERROR: Object is in wrong state
[0]PETSC ERROR:  Vec is already locked for read-only or read/write access,
argument # 1
This is in a TS callback. Does TS lock the state vector from writing?
Should I add a Read version of VecGetArrayAndMemType?
