Abstract: A method and system for providing a group of parallel resources as a proxy for a single shared resource is provided. In a preferred embodiment, a resource grouping facility (“the facility”) is incorporated in a “non-global” operating system. A non-global operating system is an operating system that is unable to respond correctly to a request to allocate a global resource of a particular type, such as a memory block, that can be accessed by every program executing in conjunction with the operating system. Instead, a non-global operating system allocates a putatively global resource that may not be accessed by every program executing in conjunction with the non-global operating system. When the facility detects that a transferer program is attempting to share a putatively global resource allocated by the operating system with a transferee program, the facility allocates a proxy resource that is accessible to the transferee.

Abstract: A computer-based custom marshaling method and system for custom marshaling of parameters during invocation of functions implemented in a second language by computer programs implemented in an first language. The parameter to be custom marshaled has a first type in the first language and a second type in the second language. The custom marshaling system receives code for converting a parameter of the first type to a parameter of the second type and for converting a parameter of the second type to a parameter of the first type. The custom marshaling system monitors the execution of a computer program implemented in the first language that invokes a function implemented in the second language. The invocation passes a parameter of the first type, and the function expects a parameter of the second type. The custom marshaling system intercepts the invocation of the function implemented in the second language.

In a preferred embodiment, a resource grouping facility ("the facility") is incorporated in a "non-global" operating system. A non-global operating system is an operating system that is unable to respond correctly to a request to allocate a global resource of a particular type, such as a memory block, that can be accessed by every program executing in conjunction with the operating system. Instead, a non-global operating system allocates a putatively global resource that may not be accessed by every program executing in conjunction with the non-global operating system. When the facility detects that a transferor program is attempting to share a putatively global resource allocated by the operating system with a transferee program, the facility allocates a proxy resource that is accessible to the transferee.

Abstract: A method and system for providing a set of routines that may be invoked by programs of two or more types is provided. In a preferred embodiment, a group of libraries that each are able to be called by programs of a different one of the types is provided. Each of the routines is provided by a function in one of the libraries. The method and system causes all of the libraries of the group to be loaded when any of the libraries of the group are loaded. In order to invoke a routine, a program calls a function in the library of the group that is able to be called by programs of its type. If the routine is provided by a function in this library, the library provides the routine itself. If the routine is provided by a function in another library of the group, the library calls the function that provides the routine in another library of the group.
