mpi_info_get_nthkey
MPI_Info_get_nthkey(3OpenMPI) MPI_Info_get_nthkey(3OpenMPI)
NAME
MPI_Info_get_nthkey - Returns the nth defined key in info.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Info_get_nthkey(MPI_Info info, int n, char *key)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_INFO_GET_NTHKEY(INFO, N, KEY, IERROR)
INTEGER INFO, N, IERROR
CHARACTER*(*) KEY
C++ Syntax
#include <mpi.h>
void MPI::Info::Get_nthkey(int n, char* key) const
INPUT PARAMETERS
info Info object (handle).
n Key number (integer).
OUTPUT PARAMETERS
key Key (string).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Info_get_nthkey returns the nth defined key in info. Keys are numbered 0...N - 1 where N is the value returned by MPI_Info_get_nkeys.
All keys between 0 and N - 1 are guaranteed to be defined. The number of a given key does not change as long as info is not modified with
MPI_Info_set or MPI_Info_delete.
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++ func-
tions 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.
