# PetscCopyMode

Determines how an array passed to certain functions is copied or retained

### Synopsis

    typedef enum { PETSC_COPY_VALUES, PETSC_OWN_POINTER, PETSC_USE_POINTER} PetscCopyMode;

      PETSC_COPY_VALUES - the array values are copied into new space, the user is free to reuse or delete the passed in array

      PETSC_OWN_POINTER - the array values are NOT copied, the object takes ownership of the array and will free it later, the user cannot change or

                          delete the array. The array MUST have been obtained with PetscMalloc(). Hence this mode cannot be used in Fortran.

      PETSC_USE_POINTER - the array values are NOT copied, the object uses the array but does NOT take ownership of the array. The user cannot use

the array but the user must delete the array after the object is destroyed.
