    • A method, system and computer program product for selectively restricting access to a program function in a computer system having an operating system security mechanism operates via an application programming interface (API) that includes a program function registration API function, an authorization selection API function, and an authorization query API function. In response to a call to the API registration function, the program function is registered in a repository in the computer system. After the program function has been registered, a system administrator can select user authorizations using a software tool that includes calls to the authorization selection API function. The system administrator may select whether a particular user or group of users is authorized to access each registered program function. A programmer can embed a call to the authorization query API function in an application program, which includes or calls the program function. When the application program reaches the call to the authorization query API function, the function is executed and returns an indicator or value indicating whether or not that user is allowed to access the program function.
    • 一种用于选择性地限制具有操作系统安全机制的计算机系统中对程序功能的访问的方法,系统和计算机程序产品通过包括程序功能注册API功能,授权选择API功能的应用编程接口(API) 和授权查询API函数。 响应于对API注册功能的调用,程序功能被注册在计算机系统的存储库中。 注册程序功能后,系统管理员可以使用包含授权选择API功能的调用的软件工具来选择用户授权。 系统管理员可以选择特定用户或用户组是否被授权访问每个注册的节目功能。 程序员可以在包含或调用程序功能的应用程序中嵌入授权查询API函数。 当应用程序到达授权查询API函数的调用时,执行该功能,并返回一个指示符或值,指示该用户是否被允许访问该程序功能。
