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.
