NAME

       MPI_Attr_put - Stores attribute value associated with a key -- use of this routine is deprecated.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Attr_put(MPI_Comm comm, int keyval, void *attribute_val)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_ATTR_PUT(COMM, KEYVAL, ATTRIBUTE_VAL, IERROR)
            INTEGER   COMM, KEYVAL, ATTRIBUTE_VAL, IERROR

INPUT PARAMETERS

       comm      Communicator to which attribute will be attached (handle).

       keyval    Key value, as returned by MPI_KEYVAL_CREATE (integer).

       attribute_val
                 Attribute value.

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       Note  that  use  of  this  routine  is  deprecated  as  of  MPI-2,  and  was deleted in MPI-3. Please use
       MPI_Comm_set_attr.  This function does not have a C++ or mpi_f08 binding.

       MPI_Attr_put  stores  the  stipulated  attribute  value  attribute_val  for   subsequent   retrieval   by
       MPI_Attr_get. If the value is already present, then the outcome is as if MPI_Attr_delete was first called
       to delete the previous value (and the callback function delete_fn was executed), and a new value was next
       stored.  The  call is erroneous if there is no key with value keyval; in particular MPI_KEYVAL_INVALID is
       an erroneous key value. The call will fail if the delete_fn function returned an error  code  other  than
       MPI_SUCCESS.

NOTES

       Values  of  the  permanent  attributes  MPI_TAG_UB,  MPI_HOST, MPI_IO, and MPI_WTIME_IS_GLOBAL may not be
       changed.

       The type of the attribute value depends on whether C or Fortran is being used. In C, an  attribute  value
       is  a  pointer (void *); in Fortran, it is a single integer (not a pointer, since Fortran has no pointers
       and there are systems for which a pointer does not fit in an integer, e.g., any   32-bit  address  system
       that uses 64 bits for Fortran DOUBLE PRECISION).

       If  an  attribute  is  already  present, the delete function (specified when the corresponding keyval was
       created) will be called.

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.
