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

INCLUDE 'mpif.h'
MPI_INFO_DUP(INFO, NEWINFO, IERROR)
        INTEGER         INFO, NEWINFO, IERROR 

 

C++ Syntax

#include <mpi.h>
MPI::Info MPI::Info::Dup() const

 

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.
