US 6,311,227 B1 · Procedure calling method

Abstract

A procedure calling method is provided, in which an appropriate procedure car be mutually called safely between separately-prepared application programs. The method uses a procedure assignment table having paired information about procedure name and procedure address. First, whether the address of a procedure corresponding to a called procedure name is included in a first procedure assignment table or not is judged. When the address of the procedure corresponding to the given name is included in the first procedure assignment table, the address of the procedure is acquired to be executed. When the address of the procedure corresponding to the given name is not included in the first procedure assignment table, whether a retrieval function for retrieving a second procedure assignment table is provided or not is then judged. When the retrieval function is not provided, an error is outputted. When the retrieval function is provided, the retrieval function is then executed to obtain the second procedure assignment table. An additional retrieval function or functions may be further provided, in which an address assignment table including paired information about the name and address of each retrieval function is preferably provided.
