VecLockReadPush#
Pushes a read-only lock on a vector to prevent it from being written to
Synopsis#
#include "petscvec.h"
PetscErrorCode VecLockReadPush(Vec x)
Logically Collective
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 generate an error.
The call can be nested, i.e., called multiple times on the same vector, but each VecLockReadPush() has to have one matching
VecLockReadPop(), which removes the latest read-only lock.
