Figure 2.2 shows the different types of handles that can be present in the handle database and the relationships between the various handle types.
圖2.2所顯示的是存在於(handle database)中不同類型的handles與它們之間的關聯性。
All handles reside in the same handle database and the types of protocols that are associated with each handle differentiate the handle type.
所有的handles存在於相同的(handle database)中,而protocols的類型是取決於每個handle中不同的handle類型。
Like file system handles in an operating system context, the handles are unique for the session, but the values can be arbitrary.
如同OS環境中的檔案系統handles一樣,handles在此期間是獨一無二的,但是數值本身是多變的。
Also, like the handle returned from an fopen function in a C library, the value does not necessarily serve a useful purpose in a different process or during a subsequent restart in the same process.
而且,在C函式庫中的fopen()函式所回傳的handle,這個值未必可運用在不同的程序,或是隨後重新啟動的相同程序中。
The handle is just a transitory value to manage state.
handle只是一種用於管理狀態的臨時數值。
