#include "petsc/private/petscimpl.h" PetscErrorCode PetscObjectComposedDataGetScalarstar(PetscObject obj,int id,PetscScalar *data,PetscBool flag)Not collective
| obj | - the object from which data is to be retrieved | |
| id | - the identifier for the data |
| data | - the data to be retrieved | |
| flag | - PETSC_TRUE if the data item exists and is valid, PETSC_FALSE otherwise |
The 'data' and 'flag' variables are inlined, so they are not pointers.
