Segmentation Fault Error in Concurrent Sensor Data Processing Simulation: What's the Issue?

My code is supposed to simulate a system where multiple sensors collect data concurrently and process them. But I get this Segmentation fault (core dumped) error thrown in my console as the code crashes. Please what am I doing wrong ?

Solution:

Seems like your

pthread_create()

pthread_create()

does not receive the correct argument, which should be the address of the SensorData struct, not the address of the value field within the struct. This part of your code : ```...

Seems like your

pthread_create()

pthread_create()

does not receive the correct argument, which should be the address of the SensorData struct, not the address of the value field within the struct. This part of your code :

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t].value);

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t].value);

Change it to pass the address of the SensorData struct instead:

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t]);

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t]);
