DMNetworkGetComponentTypeOffset

Gets the type along with the offset for indexing the component value from the component data array

#include "petscdmnetwork.h"  
PetscErrorCode DMNetworkGetComponentTypeOffset(DM dm,PetscInt p, PetscInt compnum, PetscInt *compkey, PetscInt *offset)

Not Collective

	compkey	- the key obtained when registering the component
	offset	- offset into the component data array associated with the vertex/edge point

DMNetworkGetComponentDataArray(dm, &arr); DMNetworkGetVertex/EdgeRange(dm,&Start,&End); Loop over vertices or edges DMNetworkGetNumComponents(dm,v,&numcomps); Loop over numcomps DMNetworkGetComponentTypeOffset(dm,v,compnum,&key,&offset); compdata = (UserCompDataType)(arr+offset);
