Name

MPI_Info_dup - Duplicates an info object.

Syntax

C Syntax

#include <mpi.h>
int MPI_Info_dup(MPI_Info info, MPI_Info *newinfo)

Fortran Syntax

USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_INFO_DUP(INFO, NEWINFO, IERROR)
 INTEGER  INFO, NEWINFO, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Info_dup(info, newinfo, ierror)
 TYPE(MPI_Info), INTENT(IN) :: info
 TYPE(MPI_Info), INTENT(OUT) :: newinfo
 INTEGER, OPTIONAL, INTENT(OUT) :: ierror

Input Parameter

info

Info object (handle).

Output Parameters

newinfo

Info object (handle).

IERROR

Fortran only: Error status (integer).

Description

MPI_Info_dup duplicates an existing info object, creating a new object, with the same (key,value) pairs and the same ordering of keys.

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.
