PetscMemmove

Copies n bytes, beginning at location b, to the space beginning at location a. Copying between regions that overlap will take place correctly.

#include "petscsys.h"   
PetscErrorCode  PetscMemmove(void *a,void *b,size_t n)

Not Collective

	b	- pointer to initial memory space
	n	- length (in bytes) of space to copy

a -pointer to copy space

This routine is analogous to memmove().

Since b can overlap with a, b cannot be declared as const
