In the end, the pthread_mutex_unlock() function is used to unlock the specific thread and give access to other threads. pthread_t t[2]; int i = 0; int c; pthread_mutex_lock(&ml); unsigned long i = 0; c += 1; printf("Initiated %d thread...\n", c); for(i =0; i<(0x...
In the program, we create a global named mutex. This prevents us to create more than one instances of the application on a computer. Another instance of the program can be run only after the running application finishes. Try to run the application in two different terminals. Source Mutex cla...
We can lock and unlock the piece of code using Mutex in C++. We have to assign our code between these keywords. Below we can see the syntax for better understanding while using this in our program see below; std::mutexmtx; void function_name (arugeument_if _any) { mtx.lock(); //...
