INFORMATION PROCESSING DEVICE, CONTROL METHOD THEREOF, AND RECORDING MEDIUM

An information processing device can execute a program composed of a plurality of modules including a self-module that is under the management of a module management unit and the other module that is not under the management. The module management unit 7 performs registration of a function to be notified of by a signal when an exception occurs in a program. When the signal is received if an exception occurs, exception processing is executed. At the time of loading a certain module in a process, if a function of the other module is already registered, the module management unit stores information of the function, and performs function registration to execute the exception processing with a function of the self-module instead. The same signal as the signal that the registered function receives is transmitted to the stored function of the other module.
