MPI_Type_free_keyval(3)

NAME
     MPI_Type_free_keyval - Frees the data type attribute key for the data
     type cache attribute

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Type_free_keyval ( type_keyval )
          int *type_keyval;


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER type_keyval, ierror

          CALL MPI_TYPE_FREE_KEYVAL(type_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_Type_free_keyval routine frees the data type attribute key for
     the data type cache attribute.  This routine accepts the following
     parameter:

     type_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 data types).
