LotusScript被设计为线程安全的，这意味着它使用信号量保护数据结构，从而保护装载的每个LotusScript实例。

LotusScript is designed to be thread-safe, which means it USES semaphores to protect data structures so that each loaded instance of LotusScript is protected.

args是这个信号量集数据结构中要通过IPC_SET来更新的值(在这个例子中会有解释)。

Args are the values to be updated in the semaphore set data structure through this IPC_SET (explained in the sample).

为了对信号量集数据结构进行初始化，可以使用IPC_SET命令来调用semctl系统调用。

In order to initialize the semaphore-set data structure, use the semctl system call with the IPC_SET command.
