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)
Not 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.
