MPI_Info_dup(3OpenMPI)                                                                MPI_Info_dup(3OpenMPI)



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.
