METHOD AND DEVICE MANAGING THREAD IMPLEMENTATION IN MULTITHREAD APPLICATION

PROBLEM TO BE SOLVED: To provide a method and a device for managing the interruption and the restart of a thread in an individual base. SOLUTION: An OS kernel transmits a thread stop signal to a target thread in response to a request from the thread for interrupting the execution of the target thread and a control in the target thread is moved from a normally executing program part to a signal interruption routine. The signal interruption routine, when obtaining the control, sends a service request to the kernel to stop the target thread. In response to the request from the thread for restarting the execution of the target thread, the OS kernel transmits a thread continuation signal to the target thread, posts the waiting target thread and returns the control to the signal interruption routine. The signal interruption routine, when obtaining the control again, returns the control to the program in the interruption point. COPYRIGHT: (C)2004,JPO&NCIPI
