MPI_Type_vector

Creates a vector (strided) datatype

Synopsis

#include "mpi.h"
int MPI_Type_vector( count, blocklen, stride, old_type, newtype )
int          count;
int       blocklen;
int       stride;
MPI_Datatype old_type;
MPI_Datatype *newtype;

Input Parameters

	count	number of blocks (nonnegative integer)
	blocklength	number of elements in each block (nonnegative integer)
	stride	number of elements between start of each block (integer)
	oldtype	old datatype (handle)

Output Parameter

newtype: new datatype (handle)

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) havean additional argument ierr at the end of the argument list. ierris an integer and has the same meaning as the return value of the routinein C. In Fortran, MPI routines are subroutines, and are invoked with thecall statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
