MPI_Info_dup - Duplicates an info object.
#include <mpi.h> int MPI_Info_dup(MPI_Info info, MPI_Info *newinfo)
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_INFO_DUP(INFO, NEWINFO, IERROR) INTEGER INFO, NEWINFO, IERROR
USE mpi_f08 MPI_Info_dup(info, newinfo, ierror) TYPE(MPI_Info), INTENT(IN) :: info TYPE(MPI_Info), INTENT(OUT) :: newinfo INTEGER, OPTIONAL, INTENT(OUT) :: ierror
#include <mpi.h> MPI::Info MPI::Info::Dup() const
MPI_Info_dup duplicates an existing info object, creating a new object, with the same (key,value) pairs and the same ordering of keys.
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.
