# MPI_Type_vector

Creates a vector (strided) datatype

## Synopsis

    #include "mpi.h"
    int MPI_Type_vector(
     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`) have an additional argument `ierr` at the end of the argument list. `ierr` is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the `call` statement.

All MPI objects (e.g., `MPI_Datatype`, `MPI_Comm`) are of type `INTEGER` in Fortran.
