RedHat 9 (Linux i386) - man page for mpi_info_dup (redhat section 3)

MPI_Info_dup(3) 				       LAM/MPI					      MPI_Info_dup(3)

NAME
MPI_Info_dup - Duplicate an MPI_Info object
SYNOPSIS
#include <mpi.h> int MPI_Info_dup(MPI_Info info, MPI_Info *newinfo)
INPUT PARAMETER
info - source info object (handle)
OUTPUT PARAMETERS
newinfo - destination info object (handle)
NOTES
Not only will the (key, value) pairs be duplicated, the order of keys will be the same in newinfo as it is in info . When an info object is no longer being used, it should be freed with MPI_Info_free .
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement. All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
ERRORS
If an error occurs in an MPI function, the current MPI error handler is called to handle it. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned (in C and Fortran; this error handler is less useful in with the C++ MPI bindings. The predefined error handler MPI::ERRORS_THROW_EXCEP- TIONS should be used in C++ if the error value needs to be recovered). Note that MPI does not guarantee that an MPI program can continue past an error. All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the func- tion and Fortran routines in the last argument. The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing exceptions of type MPI::Exception (but not by default). Exceptions are only thrown if the error value is not MPI::SUCCESS . Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover what the actual error value was. MPI_SUCCESS - No error; MPI routine completed successfully. MPI_ERR_ARG - Invalid argument. Some argument is invalid and is not identified by a specific error class. This is typically a NULL pointer or other such error.
