Source sentences:
text: Semaphore is simply a variable which is non-negative and shared between threads.
text: Semaphores are a shareable resource that take on a non-negative integer value.
text: When there is only one shared resource, this semaphore is used.
text: If pshared is not zero, the semaphore is shared but should be in shared memory.
text: If the value of pshared is nonzero, then the semaphore can be shared between processes.
text: The pshared argument indicates whether this semaphore is to be shared between the threads of a process, or between processes.
text: If pshared has the value 0, then the semaphore is shared between the threads of a process, and should be located at some address that is visible to all threads (e.g., a global variable, or a variable allocated dynamically on the heap).
text: If pshared is nonzero, then the semaphore is shared between processes, and should be located in a region of shared memory (see shm_open(3), mmap(2), and shmget(2)).
text: A non-zero value means the semaphore is shared between processes; a value of zero means it is shared between threads.
text: A non-zero value means the semaphore is shared between processes; a value of zero means it is shared between threads.
text: The second argument pshared indicates whether the semaphore is shared between threads of a process or between processes.
text: If pshared has the value 0, the semaphore is shared between threads of a process.
text: If the value of pshared is nonzero, then the semaphore can be shared between processes.
