VecLockReadPush#

Pushes a read-only lock on a vector to prevent it from writing

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecLockReadPush(Vec x)

Logically Collective on Vec

Input Parameter#

  • x - the vector

Notes#

If this is set then calls to VecGetArray() or VecSetValues() or any other routines that change the vectors values will fail.

The call can be nested, i.e., called multiple times on the same vector, but each VecLockReadPush(x) has to have one matching VecLockReadPop(x), which removes the latest read-only lock.
