Any of these pointers can be set to NULL on input if the corresponding infor-
mation is not needed. Else, the reference to a dummy area can be provided,
where all unwanted data will be written.
This routine is useful to get the size of a graph read by means of the SCOTCH
graphLoad
routine, in order to allocate auxiliary arrays of proper sizes. If the
whole structure of the graph is wanted, function SCOTCH graphData should
be preferred.

Description
The SCOTCH graphData routine is the dual of the SCOTCH graphBuild routine.
It is a multiple accessor that returns scalar values and array references.
baseptr is the pointer to a location that will hold the graph base value for
index arrays (typically 0 for structures built from C and 1 for structures built
from Fortran). vertptr is the pointer to a location that will hold the number
of vertices. verttab is the pointer to a location that will hold the reference
to the adjacency index array, of size *vertptr + 1 if the adjacency array
is compact, or of size *vertptr else. vendtab is the pointer to a location
that will hold the reference to the adjacency end index array, and is equal to
verttab
+ 1 if the adjacency array is compact. velotab is the pointer to a
location that will hold the reference to the vertex load array, of size *vertptr.
vlbltab
is the pointer to a location that will hold the reference to the vertex
label array, of size vertnbr. edgeptr is the pointer to a location that will
