Thread Synchronization with Semaphores
Learn how to synchronize threads with semaphores with an example.
Semaphores are typically used in sender-receiver workflows. For example, initializing the semaphore sem
with will block the receivers’ sem.acquire()
call until the sender calls sem.release()
. Consequently, the receiver waits for the notification of the sender. The program we go through when discussing one time synchronization of threads can easily be reimplemented using semaphores.
