(3M) Calculator User Manual

Fortra n users must use the PXFFILENO or FNUM functions to obtain the numbers
of the Unix file descriptors graffildes and geomfildes associated with the
logical units of the graph and geometry files.
Return val ues
SCOTCH
graphGeomSaveScot returns 0 if the graph to po logy and geometry
have be e n successfully written to grafstream and geomstream, and 1 else.

meshGeomLoadHabo
Synopsis
int SCOTCH meshGeomLoadHabo (SCOTCH Mesh * meshptr,
SCOTCH Geom * geomptr,
FILE * meshstream,
FILE * geomstream,
const char * string)
scotchfmeshgeomloadhabo (doubleprecision (*) meshdat,
doubleprecision (*) geomdat,
integer meshfildes,
integer geomfildes,
character (*) string)
Description
The SCOTCH meshGeomLoadHabo routine fills the SCOTCH Mesh structure
pointed to by meshptr with the source mesh description available from stream
meshstream in the Harwell-Boeing square elemental ma trix fo rmat [10]. Since
this mesh format does not handle geometry data, the geomptr and geom
stream fields are not used. Since multiple mesh structures can be encoded
sequentially within the same file, the string field contains the string repre-
sentation of an integer number that codes the rank of the mesh to read within
the Harwell-Boeing file. It is equal to “0” in most cases.
Fortra n users must use the PXFFILENO or FNUM functions to obtain the number
of the Unix file descriptor meshfildes as sociated with the logical unit of the
mesh file.
Return val ues
SCOTCH
meshGeomLoadHabo returns 0 if the mesh structure has been success-
fully allocated and filled with the data read, and 1 else.
