ABSTRACT:
An information processing apparatus wherein a plurality of operating systems operate on a single processor and a framework (shared object) enabling reliable and quick sharing of correct information between the plurality of operating systems is provided. The apparatus has a function the plurality of operating systems can create, register and refer to the shared object which provides an interface for registration and reference of information. The shared object is operated so that, while one of the operating systems is registering information or referring thereto, the other operating system is inhibited from registering the information and referring thereto. When one operating system finished the registration or reference of the information, one operating system informs the other operating system of the fact.
