i shud have 4 threads in my main program
1) received_data – first threads receive messages
2) process_data – whenever a message is received in first thread a signal should be sent to second thread for processing data – message id received from first thread should be used for processing data
3) health_data – this thread sends health message for every 20 seconds
4) display_data – this thread should display status in the gui.
i have written first thread which is working successfully, but am not getting idea how to send a signal when message is received and how to attach a signal handler when signal is received with the function in the second thread.
kindly suggest me for doing this
