Before actually mapping a file to memory, you must create a +memory-mapped file object by calling :ref:`PR_CreateFileMap`, which returns +a pointer to :ref:`PRFileMap`. Then sections of the file can be mapped into +memory by passing the :ref:`PRFileMap` pointer to :ref:`PR_MemMap`. The +memory-mapped file object is closed by passing the :ref:`PRFileMap` pointer +to :ref:`PR_CloseFileMap`. |
