An abstract class has at least one pure virtual function. This is standard C++ terminology.
Some people use the term pure abstract class to describe a class that has nothing but pure virtual functions
(in other words, no data members and no concrete functions). This is equivalent to Java interfaces.

http://stackoverflow.com/questions/8359322/how-to-share-semaphores-between-processes-using-shared-memory
semaphore is atomic counter which indicate the number of resource available.
Also, It is used for synchronization between threads.
sem_wait() decrements semaphore

Semaphore: Use a semaphore when you (thread) want to sleep till some other thread tells you to wake up.
Mutex: Use a mutex when you (thread) want to execute code that should not be executed by any other thread at the same time.
Spinlock: Use a spinlock when you really want to use a mutex but your thread is not allowed to sleep. e.g.: An interrupt handler within OS kernel must never sleep. If it does the system will freeze / crash. If you need to insert a node to globally shared linked list from the interrupt handler, acquire a spinlock - insert node - release spinlock.
