Otherwise, you use +functions such as :ref:`PR_Open` and :ref:`PR_NewTCPSocket` to obtain a file +descriptor, which you should treat as an opaque structure. + +For more details about the use of :ref:`PRFileDesc` and related structures, +see `File Descriptor Types <I_O_Types#File_Descriptor_Types>`__. |
