C++ Reader Writer Problem in C++ using semaphore and monitor We will focus on solving the Reader Writer problem in C++ by using Semaphores as our first approach and Monitors as our second approach. It is a problem designed to illustrate synchronization within processes.
C Programming Semaphore in C Semaphore is a data handling technique which is very useful in process synchronization and multithreading. We used the POSIX semaphore library and use the functions sem_wait, sem_post, sem_open and sem_init for implementing semaphore in C.
