Semaphore numbers flags
WebSemaphore Flags One of the most commonly used methods of visual communications is semaphore. The signalman sends messages letter by letter--generally using the same short codes contained in either the NATO or commercial signal books--by holding the two flags in various positions similar to the hands of a clock. Websemadj is a per-process integer which is simply the (negative) count of all semaphore operations performed specifying the SEM_UNDO flag. When a semaphore's value is directly set using the SETVAL or SETALL request to semctl (2), the corresponding semadj values in all processes are cleared.
