#include "mpi.h" int MPI_Graph_get ( comm, maxindex, maxedges, index, edges ) MPI_Comm comm; int maxindex, maxedges; int *index, *edges;
comm  communicator with graph structure (handle)
 
maxindex  length of vector index in the calling program (integer)
 
maxedges  length of vector edges in the calling program (integer)

index  array of integers containing the graph structure (for details see the definition of MPI_GRAPH_CREATE)
 
edges  array of integers containing the graph structure

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
All MPI routines (except MPI_Wtime and MPI_Wtick) return an error value; C routines as the value of the function and Fortran routines in the lastargument. Before the value is returned, the current MPI error handler iscalled. By default, this error handler aborts the MPI job. The error handlermay be changed with MPI_Errhandler_set; the predefined error handlerMPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can continue pastan error.
