Methods of factoring operating system functions, methods of converting operating systems, and related apparatus

One or more computer readable media comprising computer executable instructions that, when executed on a computer, direct the computer to:

• factoring a plurality of operating system functions into interface groups based upon the resources with which a function is associated;
• factoring the interface groups into interface sub-groups based upon each function's use of a handle that represents a resource;
• and
• wherein said factoring comprises creating a hierarchy of object interfaces in which certain interfaces can inherit from other interfaces, individual interface sub-groups being associated with individual programming objects that can be instantiated throughout a remote computing system and wherein the programming the programming objects include Common Object Model (COM) objects.

One or more computer readable media comprising an operating system having:

• a plurality of programming objects having interfaces, wherein the programming objects represent operating system resources, and wherein the interfaces define methods that are organized in accordance with whether they create an operating system resource or not;
• wherein the programming objects are configured to be called either directly or indirectly by an application;
• and
• wherein the methods are configured to call operating system functions responsive to being called directly or indirectly by an application;
• said programming objects being configured to be instantiated throughout a remote computing system, wherein at least some of the programming objects are disposed across at least one process boundary and at least one machine boundary and wherein the programming objects include Common Object Model (COM) objects.

One or more computer readable media comprising computer executable instructions that, when executed on a computer, direct the computer to convert an operating system from a non-object-oriented format to an object oriented format, wherein the operating system includes a plurality of operating system functions that are callable to create or use operating system resources, the converting performed by:

• defining a plurality of programming object interfaces that define methods that correspond to the operating system functions, wherein programming objects that support the interfaces are callable either directly by an application that makes object-oriented calls, or indirectly by an application that makes function calls, said programming objects being configured to be instantiated throughout a remote computing system;
• calling a programming object interface either directly via an object-oriented call, or indirectly via an indirection that transforms a function call into an object-oriented call;
• and
• responsive to said calling, calling an operating system function with a method of the programming object that supports said programming object interface, wherein at least some of the programming objects are disposed across at least one process boundary and at least one machine boundary and wherein the programming objects include Common Object Model (COM) objects.

A system comprising:

• means for factoring a plurality of operating system functions that are used in connection with operating system resources into first groups based upon first criteria;
• means for factoring the first groups into individual sub-groups based upon second criteria;
• and
• means for assigning each sub-group to its own programming object interface, wherein a programming object interface represents a particular object's implementation of its collective methods effective to provide an object-oriented operating system, wherein individual objects having associated programming object interfaces are configured to be instantiated throughout a remote computing system, wherein the programming objects include Common Object Model (COM) objects and wherein said factoring includes creating a hierarchy of object interfaces in which certain interfaces can inherit from other interfaces.

A computing device comprising:

• a processor;
• and
• memory configured to maintain one or more modules that are executable on the processor to:
• factor a plurality of operating system functions into interface groups based upon the resources with which a function is associated;
• factor the interface groups into interface sub-groups based upon each function's use of a handle that represents a resource;
• and
• wherein said factoring comprises creating a hierarchy of object interfaces in which certain interfaces can inherit from other interfaces, individual interface sub-groups being associated with individual programming objects that can be instantiated throughout a remote computing system and wherein the programming the programming objects include Common Object Model (COM) objects.
