Abstract

PURPOSE:To avoid an unnecessary dedication of various resources of a computer system and to improve the utility of various resources of the system by returning the control to a program, in case that a response from a terminal equipment to an input request from the program does not return even if a prescribed time elapses. CONSTITUTION:A terminal input control system 1 connected to a terminal input function 2 is constituted of a timer setting means 11 for requesting to a timer function to generate an interruption event after a prescribed time elapses, a timer releasing means 12 for requesting to the timer function to delete a generation request of the set interruption event, and a time-out executing means 13 for requesting to return the control. to a program operated on an electronic computer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal input control system in an information processing system, which is capable of returning control to a program when there is no response to an input request to a terminal device for a certain period of time. Regarding

[0002]

2. Description of the Related Art In the conventional terminal input control system, as shown in FIG. 2, the terminal input function 2 prompts the input to the terminal device 4 when the control is passed from the program 3, and the terminal user operates the terminal device 4 from the terminal device 4. The control of the program 3 is not returned until an input is made, and the management of the elapsed time regarding the input trigger to the terminal device 4 is left to the user of the terminal device 4.

[0003]

In the above-mentioned conventional terminal input control system, the program waits until the response from the terminal device is returned when the terminal user has been away from the desk for a long time. , There was a problem in which various resources of the computer system were unnecessarily dedicated for a long time.

The object of the present invention is to eliminate the need for various resources of the computer system by returning the control to the program when the response from the terminal device to the input request from the program does not come back even after a certain period of time. It is to provide a terminal input control method that avoids the exclusive use and improves the availability of various system resources.

[0005]

The terminal input control system described in the present invention controls the interrupt event depending on the time and the terminal input function of inputting from the terminal device requested by the program operating on the electronic computer. In a computer system having a timer function, a timer setting means connected to the terminal input function and requesting the timer function to generate an interrupt event after a lapse of a fixed time, connected to the terminal input function, When the timer function generates the interrupt event requested by the timer setting means, the timer canceling means requesting the timer function to delete the generation request of the interrupt event set by the request of the timer setting means; Timeout execution means for requesting the terminal input function to return control to the program.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a terminal input control system 1 of the present invention.

The terminal input control system 1 of the present embodiment is used by connecting to the terminal input function 2 for controlling the input from the terminal device 4, and the timer setting means 11 activated by the terminal input function 2, It is composed of a timer releasing means 12 activated by the terminal input function 2 and a time-out executing means 13 which operates by receiving control from the timer function 5 of the operating system.

The timer setting means 11 is used by being connected to the terminal input function 2, and the control is passed every time the program 3 requests the terminal input function 2 for an input from the terminal device 4 to operate. The terminal input function 2 is the timer setting means 1
The operation until the control is passed to 1 and the control is returned is as follows.

When the control is passed from the program 3 to the terminal input function 2, in the conventional case, the input request is made to the terminal device 4 as it is, and the input from the terminal user is waited. However, if the timer setting means 11 of the terminal input control method 1 of the present invention is connected, the control is passed to the timer setting means 11.

When the timer setting means 11 receives the control from the terminal input function 2, it sets the timer function 5 of the operating system so that an interrupt event occurs after a time determined by the system, and then controls the terminal input function. Return to 2.

The terminal input function 2, which has been returned to the control, makes an input request to the terminal device 4 and waits for an input from the terminal user or a notification from the timeout execution means 13.

The timer releasing means 12 is used by being connected to the terminal input function 2, and is operated by receiving control from the terminal input function 2 every time the terminal user inputs from the terminal device 4. The operation until the terminal input function 2 passes the control to the timer releasing means 12 and the control is returned is as follows.

In the terminal input function 2, the terminal user uses the terminal device 4
If it is input from, the control is passed to the program 3 as it is in the conventional case. However, when the timer releasing means 12 of the terminal input control system 1 of the present invention is connected, the control is passed to the timer releasing means 12. The timer releasing means 12 deletes the interrupt event generation request set by the request of the timer setting means 11 from the timer function 5 of the operating system and returns the control to the terminal input function 2.

The timeout execution means 13 operates by the timer setting means 11 generating an interrupt event requested to the timer function 5 of the operating system and passing control from the timer function 5 of the operating system.

When control is passed from the timer function 5, the time-out executing means 13 indicates that a certain time has elapsed in response to an input request to the terminal device 4 made from the program 3 via the terminal input function 2 by the terminal input. Notify Function 2.

The terminal input function 2 is the time-out execution means 1
When the notification is received from 3, the control is passed to the program 3 together with the information that the fixed time has elapsed in response to the input request from the program 3.

[0018]

As described above, according to the present invention, the time until the terminal user returns a response to the data input request from the program is monitored, and no response is returned even after a certain period of time. In this case, returning control to the program avoids dedicating system resources.
This has the effect of improving the availability of various system resources.
