WriteTupleHead() public méthode

Write an Erlang tuple header to the stream. After calling this method, you must write 'arity' elements to the stream or it will not be possible to decode it later.
public WriteTupleHead ( int arity ) : void
arity int The number of elements in the tuple.
Résultat void
