Conditional Variable vs Semaphore http://stackoverflow.com/questions/3513045/conditional-variable-vs-semaphore Variable vs Semaphore When should one use a semaphore and when should one use a conditional.. a binary semaphore to do this but that's a special case. Semaphores and condition variables build on top of the mutual exclusion.. particular condition e.g. for the queue to be empty . Semaphores can be used similarly but I think they're better used when..
How can I achieve something similar to a semaphore using boost in c++? http://stackoverflow.com/questions/3928853/how-can-i-achieve-something-similar-to-a-semaphore-using-boost-in-c can modify a resource between those two operations. Semaphore on another case is a mix of condition and mutex and is used.. but to synchronize access across processes. See Mutex vs Semaphore . There is also such thing as non blocking lock free synchronization..
