Assuming you on a system with documentation installed (which should
certainly be this way if it is supposed to be used for development), the
following command will often be helpful:

[rw@sable]~#apropos semaphore
IPC::Semaphore (3perl) - SysV Semaphore IPC object class
ipcrm (1)            - remove a message queue, semaphore set or shared memory id
lockfile (1)         - conditional semaphore-file creator
perlipc (1)          - Perl interprocess communication (signals, fifos, pipes, safe subprocesses, sockets, and semaphores)
SDL_CreateSemaphore (3) - Creates a new semaphore and assigns an initial value to it.
SDL_DestroySemaphore (3) - Destroys a semaphore that was created by SDL_CreateSemaphore.
SDL_SemPost (3)      - Unlock a semaphore.
SDL_SemTryWait (3)   - Attempt to lock a semaphore but don't suspend the thread.
SDL_SemValue (3)     - Return the current value of a semaphore.
SDL_SemWait (3)      - Lock a semaphore and suspend the thread if the semaphore value is zero.
SDL_SemWaitTimeout (3) - Lock a semaphore, but only wait up to a specified maximum time.
sem_close (3)        - close a named semaphore
sem_destroy (3)      - destroy an unnamed semaphore
sem_getvalue (3)     - get the value of a semaphore
sem_init (3)         - initialize an unnamed semaphore
sem_open (3)         - initialize and open a named semaphore
sem_overview (7)     - Overview of POSIX semaphores
sem_post (3)         - unlock a semaphore
sem_timedwait (3)    - lock a semaphore
sem_trywait (3)      - lock a semaphore
sem_unlink (3)       - remove a named semaphore
sem_wait (3)         - lock a semaphore
semctl (2)           - semaphore control operations
semget (2)           - get a semaphore set identifier
semop (2)            - semaphore operations
semtimedop (2)       - semaphore operations
Thread::Semaphore (3perl) - Thread-safe semaphores
