VecGetArrayWriteAndMemType

Like VecGetArrayWrite(), but if this is a device vector it will always return a device pointer to the device memory that contains this processor’s portion of the vector data.

Synopsis

#include "petscvec.h"   
PetscErrorCode VecGetArrayWriteAndMemType(Vec x, PetscScalar **a, PetscMemType *mtype)

Logically Collective; No Fortran Support

Input Parameter

• x - the vector

Output Parameters

• a - the array

• mtype - memory type of the array

Note

The array must be returned using a matching call to VecRestoreArrayWriteAndMemType(), where it will label the device memory as most recent.
