MPI_Type_create_keyval - Create an attribute keyval for MPI datatypes
Input Parameters:
+ type_copy_attr_fn - copy callback function for type_keyval (function)
. type_delete_attr_fn - delete callback function for type_keyval (function)
- extra_state - extra state for callback functions
Output Parameters:
. type_keyval - key value for future access (integer)
Notes:
Default copy and delete functions are available. These are
+ MPI_TYPE_NULL_COPY_FN - empty copy function
. MPI_TYPE_NULL_DELETE_FN - empty delete function
- MPI_TYPE_DUP_FN - simple dup function
