MPI_Comm_free_keyval - Frees the communicator attribute
key for the communicator cache attribute
SYNOPSIS
C:
#include <mpi.h>
int MPI_Comm_free_keyval ( comm_keyval )
int *comm_keyval;
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER comm_keyval, ierror
CALL MPI_COMM_FREE_KEYVAL(comm_keyval, ierror)
STANDARDS
This function is defined in the MPI-2 standard.
This release implements the MPI 1.2 standard, as
documented by the MPI Forum in the spring 1997 release of
MPI: A Message Passing Interface Standard.
DESCRIPTION
The MPI_Comm_free_keyval routine frees the communicator
attribute key for the communicator cache attribute. This
routine replaces the MPI_Keyval_free routine, which has
been deprecated. This routine accepts the following
parameter:
comm_keyval
Frees the integer key value (integer)
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS.
MPI_SUCCESS is defined in the mpif.h file.
NOTES
Key values are global (they can be used with any and all
communicators).
