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

<PRE>
typedef enum { PETSC_COPY_VALUES, PETSC_OWN_POINTER, PETSC_USE_POINTER} PetscCopyMode;
</PRE>
<P>
<pre>
PETSC_COPY_VALUES - the array values are copied into new space, the user is free to reuse or delete the passed in array
</pre>
<pre>
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
</pre>
<pre>
delete the array. The array MUST have been obtained with <A HREF="../Sys/PetscMalloc.html#PetscMalloc">PetscMalloc</A>(). Hence this mode cannot be used in Fortran.
</pre>
<pre>
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
</pre>
the array but the user must delete the array after the object is destroyed.
