    semget KEY,NSEMS,FLAGS
            Calls the System V IPC function [semget(2)](https://www.chedong.com/phpMan.php/man/semget/2/markdown). Returns the semaphore
            id, or the undefined value on error. See also "SysV IPC" in
            perlipc and the documentation for "[IPC::SysV](https://www.chedong.com/phpMan.php/perldoc/IPC%3A%3ASysV/markdown)" and
            "[IPC::Semaphore](https://www.chedong.com/phpMan.php/perldoc/IPC%3A%3ASemaphore/markdown)".
