#include "mpi.h" int MPI_Type_hindexed( count, blocklens, indices, old_type, newtype ) int count; int blocklens[]; MPI_Aint indices[]; MPI_Datatype old_type; MPI_Datatype *newtype;
count  number of blocks  also number of entries in indices and blocklens
 
blocklens  number of elements in each block (array of nonnegative integers)
 
indices  byte displacement of each block (array of MPI_Aint)
 
old_type  old datatype (handle)

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
Also see the discussion for MPI_Type_indexed about the indices in 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.
