Understand its syntax, parameters, return values, and requirements.

MPI_Type_commit function

Commits the datatype.

Syntax

int MPIAPI MPI_Type_commit(
  _In_ MPI_Datatype *datatype
);

Parameters

• datatype [in]
  Datatype to commit.

Return value

Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.

In Fortran, the return value is stored in the IERROR parameter.

Fortran

    MPI_TYPE_COMMIT(DATATYPE, IERROR)
        INTEGER DATATYPE, IERROR

Remarks

A datatype object has to be committed before it can be used in a communication. As an argument in datatype constructors, uncommitted and also committed datatypes can be used. There is no need to commit basic datatypes. They are pre-committed.

Requirements

Product	HPC Pack 2012 MS-MPI Redistributable Package, HPC Pack 2008 R2 MS-MPI Redistributable Package, HPC Pack 2008 MS-MPI Redistributable Package or HPC Pack 2008 Client Utilities
Header	Mpi.h; Mpif.h
Library	Msmpi.lib
DLL	Msmpi.dll
