CS4315 Operating Systems Lab 3: Basic Synchronization using Mutex In this lab work we will do some practice about basic synchronization. Question 1 is about creating threads and each thread runs a different function. Question 2 and 3 are about mutex lock (acquiring a lock and releasing a lock). 1. Run the following C program (tprog1.c) and observe the result on the screen. #include #include #include #include // These two functions will run concurrently void* print_i(void *ptr) { printf("I am in i "); } void* print_j(void *ptr) { printf("I am in j "); } int main() { pthread_t t1,t2; int rc1 = pthread_create(&t1, NULL, print_i, NULL); int rc2 = pthread_create(&t2, NULL, print_j, NULL); exit(0); }

3. Add mutex locks to tprog2.c to achieve synchronization, and then observe the result on your screen.
