18.2.219. MPI_Info_dup
MPI_Info_dup - Duplicates an info object.
18.2.219.1. SYNTAX
18.2.219.1.1. C Syntax
#include <mpi.h>
int MPI_Info_dup(MPI_Info info, MPI_Info *newinfo)
18.2.219.1.2. Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_INFO_DUP(INFO, NEWINFO, IERROR)
INTEGER INFO, NEWINFO, IERROR
18.2.219.1.3. Fortran 2008 Syntax
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
18.2.219.2. INPUT PARAMETER
info
: Info object (handle).
18.2.219.3. OUTPUT PARAMETERS
newinfo
: Info object (handle).IERROR
: Fortran only: Error status (integer).
18.2.219.4. 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.
18.2.219.5. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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.
