Version-marking of binary data function routines or DLLs to enable checking of consistency with a calling binary data or executable program, by incorporating a code within the DLL so that it can be checked by a calling EXE program

摘要

Method for version-marking of a binary data function routine or dynamic linked library (DLL1-3) that is called by a binary file or executable program has the following steps: creation of a version code (VC1- 3) for the DLLs and incorporation of the version code within the DLL. The method also applies to OCX files and equivalent routines in other operating systems, e.g. SO or ELF files in Linux/Unix : Independent claims are also included for the following:- (A) a method for version-marking of a function calling binary data or EXE file; (B) a method for checking the version of a DLL called by an EXE file; (C) a device for version-marking of a DLL; (D) a device for version-marking of a DLL function calling EXE file and; (E) computer program products for version-marking version checking and development of software programs.
