<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
For regular PETSc vectors this routine does not involve any copies. For
any special vectors that do not store local vector data in a contiguous
array, this routine will copy the data back into the underlying
vector data structure from the array obtained with <A HREF="../Vec/VecGetArray.html#VecGetArray">VecGetArray</A>().
<P>
This routine actually zeros out the a pointer.
