成する必要がありた。The types of applied program programs executed in the terminal control device are diverse depending on the needs of the user, and there are a large number of them. Generally, a relatively small-scale processing device (such as a Yita-shipu stomach separator) is incorporated as the control and processing means of the terminal control device. If access requests (for example, message sending) are made from a large number of application programs as described above to an input/output device connected to such a terminal control device, contention will occur. Conventionally, when creating an application program, it was necessary to create a program with consideration given to avoiding conflicts.
