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++ func-
       tions 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.
