Name

MPI_Info_create - Creates a new info object.

Syntax

C Syntax


#include <mpi.h>
int MPI_Info_create(MPI_Info *info)

Fortran Syntax


INCLUDE ’mpif.h’
MPI_INFO_CREATE(INFO, IERROR)
    INTEGER    INFO, IERROR

C++ Syntax


#include <mpi.h>
static MPI::Info MPI::Info::Create()

Output Parameters

info
Info object created (handle).
IERROR
Fortran only: Error status (integer).

Description

MPI_Info_create creates a new info object. The newly created object contains no key/value pairs.

Errors

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.

Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
