Synopsis

int MPI_Type_hvector(int count,
                    int blocklen,
                    MPI_Aint stride,
                    MPI_Datatype old_type,
                    MPI_Datatype *newtype_p)

Input Parameters

count

number of blocks (nonnegative integer)

blocklength

number of elements in each block (nonnegative integer)

stride

number of bytes between start of each block (integer)

oldtype

old datatype (handle)

Output Parameter

newtype_p

new datatype (handle)

Notes

Notes for Fortran

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

Errors

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 last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Comm_set_errhandler (for communicators), MPI_File_set_errhandler (for files), and MPI_Win_set_errhandler (for RMA windows). The MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can continue past an error; however, MPI implementations will attempt to continue whenever possible.

MPI_SUCCESS

No error; MPI routine completed successfully.
