Description
The
SCOTCH graphGeomLoadChac
routine fills the
SCOTCH Graph
structure
pointed to by
grafptr
with the source graph description available from stream
grafstream
in the
Chaco
graph format [24]. Since this graph format does
not handle geometry data, the
geomptr
and
geomstream
fields are not used,
as well as the
string
field.
Fortran users must use the
PXFFILENO
or
FNUM
functions to obtain the number
of the Unix file descriptor
graffildes
associated with the logical unit of the
graph file.
Return values
SCOTCH graphGeomLoadChac
returns 0 if the graph structure has been suc-
cessfully allocated and filled with the data read, and 1 else.
