Information processing apparatus, multitask control method, and program recording medium

Abstract

An information processing apparatus is provided wherein execution request of each task is processed so that tasks having a certain sort of attribute are not executed in parallel and are executed sequentially without conducting any special operation. When a task instructed to be executed is a task which registered extensions, which are extensions registered in the category discriminating table, do not relate to, the information processing apparatus starts execution of the task without depending on execution condition of other tasks. When a task instructed to be executed is a task which registered extensions relate, the information processing apparatus starts execution of the task if a task which registered extensions relate is not under execution. On the other hand, if a task which registered extensions relate to is under execution, the information processing apparatus queues the execution instruction of the task and execute the queued task when the task which registered extensions relate to is completed.

Dependencies are inferred from the claim text.
