Abstract:
1. An inter-task communications method achieved by execution of a computer, the inter-task communications method where a transmission request occurs, wherein the transmission request is that a data item be sent from a processing of a first task to a processing of a second task, the inter-task communications method comprising steps of: executing, when the transmission request occurs, within the processing of the first task, a data queuing so that the data item is stored in a queue from which the second task can retrieve the data item; outputting an activation request to an operating system for requesting activation of the second task; and executing, when the second task is activated by a processing of the operating system based on the activation request, a data retrieving within the processing of the second task so that the data item stored in the queue is retrieved from the queue, wherein, when a transmission request that a given data item be sent occurs, it is determined whether the queue stores a certain data item that is being already stored before the given data item is to be stored, wherein, when the certain data item is being already stored before the given data item is to be stored, no activation request is then outputted, wherein, when no certain data item is being already stored before the given data item is to be stored, an activation request is then outputted, and wherein, within the data retrieving within the processing of the second task, all data items that can be retrieved from the queue is retrieved from the queue.
